Question

What is the reason the group 13 metals have a typical charge of 3+?

Answer 1

for starters, do metals like to gain or lose electrons?

Answer 2

Answer 3

also, take a look at this interactive periodic table http://www.ptable.com

Answer 4

Gain? @Photon336

Answer 5

Remember metals like to always lose electrons, that's one of their properties.

Answer 6

all elements will either lose or gain electrons depending on their reactivity. if you look at that periodic table I posted in the link at the column starting with Helium and down group 18 those are the noble gases. all elements ideally want to have a configuration like the ideal gases because they don't react and are stable.

Answer 7

Remember, groups are organized based on how many valence electrons the elements have. Group 1 have 1 valence electron, group 2 elements have 2 valence electrons.

Answer 8

let's look at aluminum, it has 13 electrons, that's in group 13. if it has a charge of +3 it means that it looses 3 electrons; the if that's the case it has 10 electrons, what element does it's configuration resemble now?

Answer 9

are you there?

Answer 10

yes im here

Answer 11

Aluminum 3+ means that it loses three electrons to have 10 electrons; this is a noble gas configuration. The groups are organized based on the amount of valence electrons so I believe the metals in group 13 have 3 valence electrons and hence +3 would mean that they would have achieved octet.
