Why does the moon spin around the earth and the earth spins around the sun

This easy bro there is only one answer Gravity

but here my advance word

Sometimes the gravity of big objects would capture smaller ones in orbit. This could be one way the planet acquired the moon

Gravity.

Explanation: gravity is caused when something has a lot and I mean A LOT of mass, the sun has the most mass around us so we are far enough and are orbiting at the right speed so that we don’t get pulled in. Same with the moon and the earth.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
