What is the chemical formula for zinc phosphate?
solong [7]
First, we have to find the chemical formula for zinc ion and phosphate ion.

Zinc ion is a cation, and its formula is Zn^2+,
This is because zinc atom requires 2 outer shell electrons to be removed in order to become stable.

On the other hand, phosphate ion is a anion, and its formula is PO4^3-.

In order to find the chemical formula of this ionic bond, we need to make sure their charges are balanced.

To do this, take 2+ and 3-, their least common multiple is 6, so in order to turn both charges into 6+ and 6-, we need to determine how many of that ion is needed.

So to make 2+ to 6+, we need 3 zinc ions ( +2 x 3 = 6).
And to make 3- to 6-, we need 2 phosphate ions (-3 x 2 = - 6).

Now we can just combine the chemical formulas with the number of that ion needed (you can ignore the charge)
Therefore, your answer should be Zn3(PO4)2.

What is the importance of the electrons?<br> (write in one paragraph)
My name is Ann [436]
Well in everything we have protons and electrons, eg. In static electrisity in a balloon when you rub the balloon on a material like your hair all the protons come off and into your hair which makes your hair go upright and funny and the ballon is desperate to get back the protons so it sticks to surfaces to gain there protons to ballance out the electrons it allready has for it to be nuteral again. Because its important for everything that can be to be nuteral
