Question

freethinker · Answer

look at your periodic table, kid

freethinker · Answer

tell me how many valence electrons calcium has

mtalhahassan2 · Answer

ok wait for a second

mtalhahassan2 · Answer

20 maybe

freethinker · Answer

WHAT?

where is your chemistry book?

mtalhahassan2 · Answer

I don't have it yet

freethinker · Answer

freethinker · Answer

use Ebbing or Brown-Holme
Brown is shorter and simple 
Ebbing is detailed and dumbed down

freethinker · Answer

find out what valence is, valence electron and Ion

freethinker · Answer

have fun LEARNING :)

mtalhahassan2 · Answer

2

mtalhahassan2 · Answer

Calcium has 2 valence electrons, like all Group 2 elements.

freethinker · Answer

okay how many will it lose so it'll be like the noble gas group?

freethinker · Answer

you really need to download the book, because this will get more difficult and you need sample problems as a reference in the future

mtalhahassan2 · Answer

where is the book?

freethinker · Answer

mtalhahassan2 · Answer

ok

mtalhahassan2 · Answer

ok so

freethinker · Answer

so start reading any of the books in the links

mtalhahassan2 · Answer

but it too long

freethinker · Answer

so? 
Whoever follows patience, success will follow him.

freethinker · Answer

how many electrons that calcium will have to lose so it will have the same number of electrons like one of the noble gasses?

mtalhahassan2 · Answer

no idea

freethinker · Answer

freethinker · Answer

mtalhahassan2 · Answer

so it lose 2 electron

freethinker · Answer

okay so what happens with the ion when it loses two electrons? 
you have more positive than negative now

mtalhahassan2 · Answer

electrons making it have a charge of + 2 or Ca+2
