He partial lewis structure that follows is for a hydrocarbon molecule. in the full lewis structure, each carbon atom satisfies the octet rule, and there are no unshared electron pairs in the molecule. the carbon-carbon bonds are labeled 1, 2, and 3. part a how many hydrogen atoms are in the molecule?

Hydrocarbon molecule is a type of molecule which is composed of hydrogen and carbon atoms. Carbon atom belongs to group 4 in the periodic table which means it has four electrons in its outermost shell or orbit, so for attaining octet rule, carbon atom makes 4 covalent bonds with 4 hydrogen atoms and 4 electrons of hydrogen atom is used by the carbon atom and becomes a stable molecule.

Hydrocarbon:

A hydrocarbon is class of organic chemicals made up of only the elements carbon (C) and hydrogen (H).
The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations.

Now consider the Lewis dot structure of CH₄ i.e. the simplest hydrocarbon attached below

The electron dot structures are used to show the bond formation among the elements of a covalent chemical compound. Similarly, the CH₄ is also a covalent compound.
There are 4 valence electrons of the central carbon atom and each of the four hydrogen atoms have 1 valence electrons.
