No number is writeen in writing a formula when the valence numbers of both the metals and nonmetal in a compound are 1.
If you do know the answer, could you please explain this to me. I have absolutely no idea what it means?

H2O
You don't write a number next to "O" because there's only 1 oxygen atom.
So it's true.

For the compounds as NaCl we do not write
Na1Cl1 but only NaCl
Also for CaO ( two valences both) we do not write Ca1O1

FALSE. As long as either or both the anionic and cationic part of the compound have just one unit in it, the subscript 1 is not used. For example: H2O, HCl, NH3.

The combination or bonding results from the valence charge. A plus one and a negative one combine to zero net charge.

It is a statement
Exaample also in orbitals sp3 is a mixed orbital of 1 orbital s and 3 orbitals p

False,
Although it may seem that we write so but there are counterexamples too
eg.
1) Cu2Cl2 (cuprous chloride)
2) Hg2Cl2 (mercurous chloride)
