How many protons, neutrons, and electrons are in 195Pt2+ ?

1 answer:

4 0

Answer:

The answer to your question is Protons = 78, Neutrons = 117, Electrons = 76

Explanation:

¹⁹⁵Pt²⁺

Protons are equal to the atomic number, Platinum has an atomic number of 78 so the number of protons = 78.

The number of neutrons = Mass number - Number of protons

= 195 - 78

= 117

The number of electrons is equal to the number of protons - two, we know this because of the 2+ exponent next to the Platinum symbol.

Number of electrons = 78 - 2

= 76

All the given compounds are basic on acidifying their solubility increases.

<u>Explanation:</u>

$C a_{3}\left(P O_{4}\right)_{2}$ solubility will increase, since it is basic in nature, on acidifying solubility increases.
$F e S$ being basic on acidification, the solubility increases.
$M g C O_{3}$ is alkaline in nature, it gets neutralized and there is no increase in acidity.
$M g B r_{2}$ is a salt and it shows no effect on acidification.
$A g I$ is a salt but insoluble in water and shows no effect on acidification.
$M g(O H)_{2}$ is strongly basic in nature, on acidifying the solubility increases.
