Question

periodic table high school reference sheet
an atom x has three electrons in its outermost shell. which ion will most likely be formed by x?
a. x²-
b. x³-
c. x²+
d. x³+

Explanation:

Step1: Determine the ion - forming tendency

Atoms with 1 - 3 electrons in the outermost shell tend to lose electrons to achieve a stable electron configuration.

Step2: Calculate the charge of the ion

Since atom \(X\) has three electrons in its outermost shell, it will lose three electrons. When an atom loses electrons, it forms a positive ion. The number of electrons lost is equal to the positive charge on the ion. So the ion formed will be \(X^{3 +}\).

Answer:

D. \(X^{3+}\)
