Best ResponseYou've already chosen the best response.1ok 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

Best ResponseYou've already chosen the best response.0there are 8 p+ and 8 e right?

Best ResponseYou've already chosen the best response.1I knew that protons and neutrons equaled. I think that the number is 8protons and 10 neutrons

Best ResponseYou've already chosen the best response.0Did you use the ask the (MAN) formula

Best ResponseYou've already chosen the best response.1to 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

Best ResponseYou've already chosen the best response.1ok well what about this SAY if I had fluorine with a minus charge how many protons and electrons does this have? dw:1443668752177:dw

Best ResponseYou've already chosen the best response.1oh 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?

Best ResponseYou've already chosen the best response.0Its charge would be positive I think

Best ResponseYou've already chosen the best response.1@emmynimmy where is hydrogen located? first of all on the periodic table? and what is it's atomic number?

Photon336

Best ResponseYou've already chosen the best response.1can you tell me what this means in terms of how many electrons and protons @emmynimmy what about you @8054manofwar

Best ResponseYou've already chosen the best response.0It has 1 p+ and 1 e and then 0 neutrons right

emmynimmy

Best ResponseYou've already chosen the best response.1yeah what they said ^^ sorry i was typing.

Best ResponseYou've already chosen the best response.1@emmynimmy do you agree with @8054manofwar why is he right so far?

Photon336
 one year ago
Best ResponseYou've already chosen the best response.1so how many protons and electrons does hydrogen have @emmynimmy

Photon336
 one year ago
Best ResponseYou've already chosen the best response.1ok so if hydrogen loses it's electrons what is it's charge now?

anonymous

Best ResponseYou've already chosen the best response.0Wait I know the answer emmy. Use the MAN formula

emmynimmy
 one year ago
Best ResponseYou've already chosen the best response.1because there is one proton

Photon336

Best ResponseYou've already chosen the best response.1so the first thing you do is this, you write out how many protons and electrons hydrogen has dw:1443669221490:dw

Best ResponseYou've already chosen the best response.1@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?

Photon336
 one year ago
Best ResponseYou've already chosen the best response.1yes can you tell me why though? by writing it out

emmynimmy
 one year ago
Best ResponseYou've already chosen the best response.1because there is still a proton.

Best ResponseYou've already chosen the best response.1yeah no problem take care

Best ResponseYou've already chosen the best response.1last thing though Cation's and Anions, the number of electrons changes
