What are proteins? (simple definition please)

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Hope this helps!

Proteins are carbohydrates that come from nutritious food.

They are one of the four main carbohydrates.

This is a simple definition of the word proteins.

Hope this helps!

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

a electronegativity decreases beacuse the size of nucleus is bigger.
