which molecules show an appropriate number of bonds around each carbon atom? select the three that apply.
iren2701 [21]

The appropriate number of bonds around each carbon atom are four covalent bonds

Please note that carbon has four valence electrons in its outermost shell

<h3>What is an element?</h3>

An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.

An atom is the smallest unit or part of an element which can take part in a chemical reaction.

On a general note, elements are classified as thus:

  • Metals, non-metal, and metalloid.

  • The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.

  • However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,

So therefore, the appropriate number of bonds around each carbon atom are four covalent bonds

Complete question:

What is the appropriate number of bonds around each carbon atom?
