Particle P: Non-charged particle Particle Q: Positively charged particle

Which of the following statements is correct based on the descriptions of each particle? (4 points)

a
Particle P is an electron and Particle Q is a proton.

b
Particle P is a neutron and Particle Q is an electron.

c
Both particles are inside the nucleus of the atom.

d
Both particles revolve around the nucleus of the atom.

answer is option b

Explanation:

because particle p is a neutron and particle q an electron

- 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
