Question

multiple - choice question
what property of carbon makes it so versatile?
it has 4 valence electrons
its very reactive
it is electronegative
its in a high period on the periodic table

Explanation:

Carbon has 4 valence electrons, allowing it to form a wide variety of stable covalent bonds with many elements, which is the main reason for its versatility. It is not extremely reactive under normal conditions, its electronegativity is not the key factor for its versatility compared to the valence - electron property, and it is not in a high period (it is in period 2).

Answer:

It has 4 valence electrons
