Question

question 1 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 1+ b 1- c 38 d 37

Explanation:

Step1: Understand electron - charge relationship

Electrons have a negative charge. Losing an electron means losing a negative charge.

Step2: Determine ion charge

When an atom loses 1 electron, its charge becomes 1+ because it has one more proton (positive charge) than electrons.

Answer:

A. 1+
