What is [AlCl₆]³⁻?

[AlCl₆]³⁻ is a group of atoms that act like a team working together, one big clump made from aluminum and chlorine.

Imagine you have a toy box, and inside it are six climbers (chlorine) holding hands around one leader (aluminum). Together, they form a strong group, and because of how they’re connected, this whole team has a little extra charge, like if the leader had three extra marbles in their pocket.

Aluminum usually gives away three electrons when it joins with others. Each chlorine grabs one electron from aluminum to make itself happy. With six chlorines around one aluminum, that makes three extra negative charges (because each chlorine has a little bit of extra charge too).

So instead of being alone, the aluminum and its six climbers become a charged clump, called [AlCl₆]³⁻, like a supergroup with a team name![AlCl₆]³⁻ is a group of atoms that act like a team working together, one big clump made from aluminum and chlorine.
