Use the periodic table to identify the number of valence electrons available for bonding for each of the following elements. c: h: n:

The number of valence electrons of carbon are 4, nitrogen are 5 and hydrogen are 1.

Explanation:

Valence electrons are defined as the electrons which are present in the outermost shell of an element. It is determined from the electronic configuration of an element.

The electronic configuration of the given elements are:

1. Carbon: Number of electrons in this element are 6.

The electronic configuration of carbon:

The number of valence electrons are 4.

2. Hydrogen: Number of electrons in this element are 1.

The electronic configuration of hydrogen:

The number of valence electrons are 1.

3. Nitrogen: Number of electrons in this element are 7.

The electronic configuration of nitrogen:

The number of valence electrons are 5.

Hence, the number of valence electrons of carbon are 4, nitrogen are 5 and hydrogen are 1.
