Question

question 25 of 25
rubidium (rb) has an atomic number of 37. it can lose 1 electron to form an ion. what would its charge be?

a. 38
b. 37
c. 1−
d. 1+

Explanation:

An atom is neutral with equal protons (atomic number) and electrons. When Rubidium (Rb) loses 1 electron, it has 1 more proton than electrons. Protons are positive, so losing an electron (negative charge) makes the ion have a positive charge. Losing 1 electron gives a charge of \(1+\).

Answer:

D. 1+
