@emmynimmy what do you think the answer is
okay so i'll show you how to do it step by step if you're willing to actively participate
I get that
@emmynimmy so far follow?
Yeah I understand.
ok now for every element we have two numbers: the atomic number and the mass number. usually for every element the number of protons = the number of electrons. so positive charges = negative charges which makes it neutral. |dw:1443668234799:dw|
yeah I understood that
That makes sense, so positive cancels negative got it
okay great @8054manofwar and @emmynimmy next thing
what we need to do is for oxygen 18.
|dw:1443668415142:dw| can you guys tell me how many protons and electrons are in oxygen based off of what i said? @emmynimmy @8054manofwar
and also how do you know this?
there are 8 p+ and 8 e- right?
I knew that protons and neutrons equaled. I think that the number is 8protons and 10 neutrons
@8054manofwar @emmynimmy yep you guys got it and last thing
wait so was my answer correct?
Did you use the ask the (MAN) formula
to find the number of neutrons, you ALWAYS subtract the top number from the bottom that is the mass number from the atomic number. |dw:1443668631307:dw| so this element has 8 protons, 8 electrons and 10 neutrons. @emmynimmy @8054manofwar
do you guys know about cations and anions?
awesome! Thank you so much!
yes I do
sorry guys i know this isn't a chem question but i was wondering how can i post another question I have?
ok well what about this SAY if I had fluorine with a minus charge how many protons and electrons does this have? |dw:1443668752177:dw|
@emmynimmy you can post it here or open up another question
how do i open another question?
well you would have to close this question
oh ill just ask you guys then! So I don't know this, the question is If an atom of hydrogen loses its electron, what is its charge?
17 p+ and 18 e-
Its charge would be positive I think
+2 –1 +1 0
thats the answer choices.
@8054manofwar yeah your correct @emmynimmy okay for this, lets look at this
@emmynimmy where is hydrogen located? first of all on the periodic table? and what is it's atomic number?
atomic number is 1
can you tell me what this means in terms of how many electrons and protons @emmynimmy what about you @8054manofwar
It has 1 p+ and 1 e- and then 0 neutrons right
yeah what they said ^^ sorry i was typing.
@emmynimmy do you agree with @8054manofwar why is he right so far?
Idk i read it.
so how many protons and electrons does hydrogen have @emmynimmy
ok so if hydrogen loses it's electrons what is it's charge now?
Wait I know the answer emmy. Use the MAN formula
because there is one proton
so the first thing you do is this, you write out how many protons and electrons hydrogen has |dw:1443669221490:dw|
Mann- Atomic Number=Neutrons
@emmynimmy the number of protons is always equal to the number of electrons. right it out like this protons have a positive charge + electrons have a negative charge - follow?
so would it be 1+?
yes can you tell me why though? by writing it out
because there is still a proton.
awesome thank you both so much you guys are awesome!
yeah no problem take care
See u later guys
last thing though Cation's and Anions, the number of electrons changes
