Question 2 of 20

Based on their locations on the periodic table, which two elements would you
expect to form positive ions with a +3 charge?
A. Nitrogen, N.
B. Boron, B
C. Phosphorus, P
D. Aluminum, Al

Answer 1

Aluminium & Phosphorus (C & D)

Step-by-step explanation:

Both these elements need to form positive ions with a +3 charge as they need to lose their 3 electrons to form a stable state in their configuration.

Answer 2

A

Because Aluminum atoms tend to lose electrons in order to achieve an insert gas configuration. The aluminum atoms need to lose 3 electrons in order to attain the neon configuration , so it forms a trip of positive action
