Nitrogen has atomic number

A nitrogen atom has electrons in its outermost electron shell.

A nitrogen atom can form covalent bonds with other atoms.

Rank the following atoms from most electronegative to least electronegative: $C,N,O,H.$

These two diagrams are examples of single covalent bonds between two atoms. Draw the electrons of each bond as dots. Think carefully about where to place the dots.

$C-H$

What is the total number of carbon atoms in this molecule?
