Question 1 options: potassium forms ions with a charge of +1 (k+). iodine forms ions with a charge of -1. selenium forms ions with a charge of -2 ( imagine that potassium ions and selenide ions combine to form potassium selenide. what numbers would be in the place of x and y in: kxsey (use the number 1 even if it isn't strictly necessary)

Given:

Charge on potassium (K) = +1

Charge on selenium (Se) = -2

To determine:

The values of X and Y in K(X)Se(Y)

Explanation:

The molecule which is formed between K and Se is neutral.

The K+ and Se2- ions should combine such that the net charge on the molecule is zero.

X(K+) + Y(Se2-) = 0

X(+1) + Y(-2) = 0

The simplest solution to the above equation is obtained when X = 2 and Y = 1

Thus, the molecule would be: K₂Se₁

Ans: X = 2 and Y = 1; K₂Se₁

The South would destroy the nation, so the North had to fight for the nation’s survival.

no but i do not usually comment or use my voice that much when it comes to social media

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
