Question

How many valence electrons does carbon have and why is it important?

Answer 1

Explanation:

1)

Valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules. The electrons present in the outermost shell are called valence electrons. Carbon has four valence electrons and here a valence of carbon is four.

2)The brain uses glucose and ketone bodies for energy. Adipose tissue uses fatty acids and glucose for energy. The liver primarily uses fatty acid oxidation for energy. Muscle cells use fatty acids, glucose, and amino acids as energy sources.

3)Amino acids are chemical compounds consisting of a carbon atom bonded to an amine group, a hydrogen atom, a carboxylic group, and a varying side-chain (R group); it is this side chain that distinguishes each amino acid from another.

pls it will help full for me

Answer 2

Answer:

Q1. 4

Q2. amino acids: carbon, hydrogen, oxygen, nitrogen sometimes sulphur and phosphorous

fatty acids: Carbon, Hydrogen and Oxygen

Glucose: Carbon, Oxygen and Hydrogen

Q3. By the chemical properties in their R group

Explanation:

Q1. electronic configuration of carbon: 2,4 so it need 4 more electrons

Q2. Each of them have carbon, hydrogen and oxygen in common but do remember that each of them have different amounts of each of the elements
