How do I find the number of electrons in an element?

It's on the periodic table

What is the element?

If I had my table on me I could tell you where it is.
❌❌ѦяƬяʏĦαя∂❌❌ Sep 2, 2012

Well I have a list of the elements there is a whole bunch. And I know that if an element has the same # of protons and electrons that makes it an atom. But how am I suppose to know if it's an atom or not if they only give you the protons?
ℒƬ. ʗøℒʊℳℬɵ Sep 2, 2012

The atomic number is on the top left of the square. That will tell we the numbe of protons and electrons that the element has.

I believe it's the atomic number. Correct me if I'm wrong (been a few months since chem)

Don't worry, you are from a A student. What Im worried about is that he is using this for his homework.👍

What level of Chemistry are you in?
❌❌ѦяƬяʏĦαя∂❌❌ Sep 2, 2012

Ik that the atomic number is the number of protons. And that an atom has the same number of protons and electrons. But if it's an ion then they would be different numbers. So the question is asking how many electrons there are in this element without telling you if it's an ion or an atom.

I wouldn't worry about it. The stuff that he would be asking is adding equations.

SnO2(s)+ 2H2(g) ---> Sn(s) + 2 H2O(g)

Grr I didn't like this stuff at first. I passed with a 67 so I re did it and got a 86 :)
ℒƬ. ʗøℒʊℳℬɵ Sep 2, 2012

Here is an example
(just pretend)

Di+= 1 more proton than electron
DI-= 1 more electron than proton
Di2- 2 more electrons than protons

I better review my notes from last year. I'm dropping my chem20IB course (marks of 85+) for Chem20 (75+) but I'm not remembering the balancing too well.

It's fine. This stuff is confusing as heck. Just finding the Jules of something is hard enough.

What chemistry class are you in? The electrons don't have to be similar- ever been taught anything to do with ions?

Redoing it is nice- easy going teacher? I got a 97 though So I was fine...

Funny thing, me too.

We have learned about ions but the sheet that was given to me doesn't give you the electrons so I have no idea is the element is a ion so I guess it has to be an atom.

It's not like that. If an element is lacking an electron, your count of electrons is off, the atom is still the same and it has a +1 ion on the atom. The electron count is not what decides the element of the atom

Uggggh.

Electrons for all practical purposes have relatively no mass. They do not contribute to atomic mass.

The atomic mass is protons and neutrons.

Atomic number is just protons.

Charge is dictated by the balance of electrons and protons.

Valence electrons frequently come and go, which is how electricity (electrons) flows through conductors.

Electrons do not come in fixed amounts. If you remove them, it does not change the element, only its' charge.

You people are actually taking chemistry classes and you don't know this yet?

To make a balanced atom, the number of protons equal the amount of electrons. Otherwise, you would have an imbalanced atom, which in-turn would attract itself to another atom of like-properties like a magnet, but all of this varies in certain instances.
