Kim described two subatomic particles below:

particle p: has the least mass
particle q: a more massive particle with a charge

which of the following statements is correct based on the descriptions of each particle?

a.) particle p repels particle q.
b.) particle p attracts particle q.
c.) particle p is a neutron and particle q is a proton.
d.) particle p is a proton and particle q is an electron.

Explanation:

Given that has least mass.

Since electron has a negligible mass, can be taken as electron.

Given that is more massive with a charge.

Since proton is more massive than electron and is also charged,

we can take as proton.

Since proton is positively charged and electron is negatively charged,both of them attract each other.

So,particle attracts particle .

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
