Question

Choose the statements that are true about hydrogen.A. Oxygen and hydrogen together can make water.B. Hydrogen has a total of three electron shells.O C. A full valence shell for hydrogen is two electrons.OD. If one hydrogen atom bonds to one oxygen atom, the atoms donot both have full valence shells.SUBMIT

Answer 1

A. Oxygen and hydrogen together can make water

C. A full valence shell for hydrogen is two electrons

Step-by-step explanation:

Answer 2

option A and C are correct

EXPLANATION

Hydrogen is a gas of diatomic molecules. Hydrogen is the lightest element with the atomic number of 1

A. Yes, hydrogen atom and oxygen atom can form water

Hydrogen can bond with oxygen to produce water

`\text{ H}_2\text{ }+\text{ }(1)/(2)O_2\text{ }\rightarrow\text{ H}_2O`

Water molecules has 2 atom of hydrogen and 1 atom of oxygen

Hence, it is true

B. No, hydrogen does not have a total of three electrons shell. The atomic number of hydrogen is 1, and therefore, it has one shell with one valence electron.

Hence, it is false

C. A full valence shell for hydrogen is two electrons. Since hydrogen atom has one valence electrons and it need two electron to have full valence shell.

Hence, it is true

D. if one hydrogen atom bonds with one hydrogen atom, the atom atoms do not both have full valence shells

This is false because hydrogen atom required one valence electrons for filling and oxygen needs two valence electrons for filling. If the two atoms bond together, hydrogen will get it full filling while oxygen atom will be incomplete.

Hence, the statement is false

Therefore, option A and C are correct
