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

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.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
