How Do You Name An Covalent Compound

The rules for naming binary covalent compounds are as follows: First, identify the element name of the nonmetal that is farthest to the left and farthest to the bottom of the periodic table. Second, use the element name for the other nonmetal, but shorten it and add a -ide ending.

What are the two rules for naming covalent molecules?

The rules for naming binary covalent compounds are as follows: First, identify the element name of the nonmetal that is farthest to the left and farthest to the bottom of the periodic table. Second, use the element name for the other nonmetal, but shorten it and add a -ide ending.

What is the rule for naming compounds?

A molecular compound is usually composed of two or more nonmetal elements. Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.

When naming a covalent compound what is the first element?

Rule 1. The element with the lower group number is written first in the name; the element with the higher group number is written second in the name. Exception: when the compound contains oxygen and a halogen, the name of the halogen is the first word in the name.

How do you name covalent compounds with three elements?

Naming covalent compounds with three elements follows these similar rules. As you would in the other cases, specify the formula, charge and number of each ion. For example, lithium hydrogen phosphate contains three elements: lithium, which is a cation, and hydrogen phosphate. Therefore its name is Li4HPO4.

What are 5 examples of covalent compounds?

Here are some examples of covalent compounds [19]:

  • Hydrogen (H2) Hydrogen (H) is the simplest of all elements. …
  • Oxygen (O2) …
  • Nitrogen (N2) …
  • Water (H2O) …
  • Carbon Dioxide (CO2) …
  • Methane (CH4) …
  • Ammonia (NH3) …
  • Carbon Monoxide (CO)

Is H2O a ionic or covalent?

Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule.

What is covalent bond with example?

These electron pairs are known as shared pairs orbonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. example could be “Water, H2O” as it is formed by the share of electrons of hydrogen and oxygen (which are both non-metals).

What describes a covalent bond?

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

What are the three rules for naming ionic compounds?

Rules for naming simple ionic compounds.

  • Name the metal by its elemental name.
  • Name the nonmetal by its elemental name and an -ide ending.
  • Name polyatomic ions by their names.

Do you use prefixes when naming covalent compounds?

In naming covalent compounds, each element in a covalent compounds needs a prefix to denote the number of atoms of that element. These prefixes are Greek (mon-, di-, tri-, etc) and the last element in the formula also gets the suffix “-ide.”

How do you arrange covalent compounds?


  1. Determine the total number of valence electrons in the molecule or ion. …
  2. Arrange the atoms to show specific connections. …
  3. Place a bonding pair of electrons between each pair of adjacent atoms to give a single bond.

How do you name a ionic compound?

Ionic compounds are named by stating the cation first, followed by the anion. Positive and negative charges must balance. Some anions have multiple forms and are named accordingly with the use of roman numerals in parentheses. Ternary compounds are composed of three or more elements.

What is the name of the covalent compound H2O?

Naming Binary Molecular Compounds

What are rules for naming inorganic covalent?

The atom farthest to the left on the periodic table is named first. Place the elements in their proper order. The element farthest to the left in the periodic table is usually named first. If both elements are in the same group, the element closer to the bottom of the column is named first.

What are the 4 types of covalent bonds?

The pair of electrons participating in this type of bonding is called shared pair or bonding pair. The covalent bonds are also termed as molecular bonds.

Types of Covalent Bonds

  • Single Covalent Bond.
  • Double Covalent Bond.
  • Triple Covalent Bond.

Is co2 a covalent bond?

Carbon dioxide (co2) features a polar covalent bond.

Is co2 ionic or covalent?

No, CO2 is not an ionic compound. As per the definition, an ionic compound is a compound that is mostly formed between a metal atom and a non-metal atom. Meanwhile, CO2 is a compound that is formed between two non-metal atoms (carbon and oxygen) thus giving it a covalent nature.

Is NH3 covalent or ionic?

NH3 is a covalent bond. This is because, Nitrogen and Hydrogen have shared the electron. The main difference between an ionic and covalent bond is ionic bond will donate or accept electron.

Is o2 covalent or ionic?

Oxygen forms a covalent bond with itself, since oxygen gas is just two oxygen atoms bonded together with a covalent bond.

Is NaCl covalent or ionic?

Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl.

Which one of the following is a covalent compound?

The Correct Answer is Carbon tetrachloride.

What are 5 characteristics of covalent compounds?

Characteristics of covalent compounds

  • Covalent compounds are made up of neutral molecules. …
  • The melting and the boiling points of covalent compounds are generally low. …
  • Covalent compounds are insoluble in water but soluble in organic solvents.
  • Covalent compounds do not conduct electricity.

Which is most likely a covalent compound?

That means the closer the electronegativities of the atoms involved, the more likely they will be sharing their electrons rather than one atom taking the electrons of the other. Thus, the compound that is most likely covalent is the one with the atoms that have the smallest difference in electronegativity.

When covalent bond is formed?

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

How many covalent bonds are formed?

Typically, the atoms of group 4A form 4 covalent bonds; group 5A form 3 bonds; group 6A form 2 bonds; and group 7A form one bond. The number of electrons required to obtain an octet determines the number of covalent bonds an atom can form.

What is formation of covalent compounds?

A covalent compound is made when two or more nonmetal atoms bond by sharing valence electrons. The shared valence electrons between two nonmetal atoms is called a covalent bond. Covalent bonds are formed when two atoms begin sharing electrons.

Why are Greek prefixes used in covalent compounds?

Greek prefixes (see the Table provided at the bottom of this page) are used to indicate the number of atoms of each nonmetal element in the chemical formula for the compound. Exception: if the compound contains one atom of the element that is written first in the name, the prefix “mono-” is not used.

Which is one basic rule when writing the name of an ionic compound?

For a basic ionic compound, (one that uses a metal cation and a non-metal anion) the metal cation simply uses the name of the element, and the non-metal anion uses the name of the element with the suffix changed to -ide.
