How many protons, neutrons and electons are in this...?

Question

59(superscript) Ni 2+(superscript
28(subscript)

Please help...I hate chem homework and need to learn how to do this!

so the problem kind of looks like this...

59 2+
Ni
28

please help!!!

59 2+
Ni
28

thats better actually!

Answer 1

Ok, here we go.

The atomoic number of Ni is 28 (periodic table), therefore the number of protons is 28. The atomic weight is 59 therefore the number of neutrons plus protons is 59. 59-28=31 neutrons

I'm assuming the Ni has a 2+ charge, so the number of electron would be 26.

Ion charge = #of protons - # of electrons
+2= 28 - # electrons

Answer 2

ok
the 59 is the atomic mass. This is the total number of protons and neutrons in the atom
the 28 is the atomic number. This is the total number of protons in the atom.
the 2+ is the charge. This relates to the number of electrons. A proton is positive and an electron is negative. When the protons and electrons are equal, the charge is zero.

so to answer your question. 28 protons, 59-28 = 31 neutrons, 28-2 = 26 electrons. to determine the number of electrons, subtract the charge from the number of protons. If say it were
super 16 O super2-
sub 8
it would be 8 protons, 8 neutrons, and 16 - (-2) = 18 electrons

Answer 3

59 is the mass # of the nickel(Ni) ion which is the same even if it is the atom. the2+ is the net charge of the ion resulting from unequal #s of protons(+-ve) and electrons(--ve). In a Ni atom the# of protons= the# of electrons and is given by the atomic# (28) This means that the atom has a net charge of 0 If the atom losses 2 electrons it means that it has 2 extra positive(+-ve) charges thus the2+. Try to be more +-ve with chemistry.I know it's hard sometimes but you can make it if you'r patient.Oh by the way,the # of neutrons=the mass # - the proton # since the masses of the protons and neutrons constitute the mass of the atom/ion.Thus 59-28=31nuetrons

Answer 4

well ni 2 means that there are two ni atoms so all you have to do is double the atomic number which gives you the protons and electrons, then you subtract the atomic weight by the protons to give you the neutrons
