This one might be easier to do if you drew a picture of the atoms. I have drawn them for you and attached the screenshots below (The black dots represent the Valence electrons). Carbon has 4 valence(outer) electrons, but most atoms seek to have 8 valence electrons. Some molecules, like carbon, obtain these extra electrons by sharing them with other atoms. When electrons are shared between two atoms that is called a covalent bond. So, carbon needs 4 more electrons to make it stable. Each hydrogen has 1 valence electron, but seeks to have two valence electrons to make it more stable. In the final image you can see that carbon can make 4 covalent bonds with 4 hydrogen atoms. I hope everything made sense! If not comment with any questions below!

A carbon atom can form 4 covalent bonds with 4 hydrogen atoms.

Explanation:

Covalent bond is a type of chemical bond in which electrons are shared between the atoms.
Shared pairs of electrons are in the center of the bond of the two atoms.

Given:

Carbon atom has 4 electrons in its outermost electron shell

Hydrogen atom has 1 electron in its outermost electron shell

To find:

Number of covalent bonds of carbon with hydrogen atoms.

Solution:

The carbon has 4 electrons in its outmost electron shell which means it can either lose or gain four electrons to attain stability of noble gas.

For this carbon atom will share its four electrons in the form of a covalent bond.

The carbon atom in order to complete its octet will form four covalent bonds with four hydrogen atoms. In which 4 electrons of carbon will be shared among the four hydrogen atoms respectively.

And along with this hydrogen atom's octet will also get complete resulting in the formation of [tex]CH_4[/tex] molecule. (as in the image attached)

So, a carbon atom can form 4 covalent bonds with 4 hydrogen atoms.
