Which statement accurately describes the illustration? a. hydrogen has a valence of 1 and oxygen has a valence of 8 b. hydrogen has a valence of 1 and oxygen has a valence of 2 c. hydrogen has a valence of 2 and oxygen has a valence of 6 d. hydrogen has a valence of 1 and oxygen has a valence of 6

A. Hydrogen has a valence of 1 and Oxygen has a valence of 8.

Explanation:

Meaning that oxygen has 8 valence electrons in its outer shell and hydrogen has 1 valence electron in its outer shell

D. Hydrogen has a valence of 1 and oxygen has a valence of 6

Explanation:

Electrons present in the outer most shell of an atom is known as valence electrons.

Here oxygen has 6 valence electrons in its outermost shell while hydrogen has only one valence shell in its outermost shell

So here if hydrogen share its one electron with oxygen then its electron configuration becomes stable and if oxygen share its two electrons of the shell with two different hydrogen atoms then this will stable the electron configuration of oxygen.

So in this way hydrogen and oxygen forms bonds with each other and its bond sharing electrons will form bond.

so here correct answer will be

D. Hydrogen has a valence of 1 and oxygen has a valence of 6

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
