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

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

Aluminium & Phosphorus (C & D)

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.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
