What three (3) factors determine the reactivity of elements? Explain and give examples of each.

1 answer:

6 0

Three factors that determine the reactivity of elements are the valence electrons are the electrons in the outermost electron shell of an atom. The number of electrons in an atom's outermost valence shell governs its bonding behaviour. That is why in periodic table the elements were put together according to their numbers of valence electrons.

METALS

The most reactive kind of metallic element is a metal from Group 1 sodium or potassium.

An atom in Group 1 has only one valence electron.

NON-METALS

A nonmetal tends to attract another valence electrons to attain a full valence shell.

kolbaska11 [484]

Answer:

c. A to K

Explanation:

If the alanine mutation is restored to K or lysine residue, most likely the wild type level of activity can be restored. This is because, arginine and lysine have -NH2 as the functional group. So, functional similarity of arginine can be expected from lysine as well.

Hence the correct option is c that is A to K.
