Plus 9, zero, minus 9 respectively.
Electrons have a negative charge, protons have a positive charge... Every electron cancels out the charge of a proton so if you subtract electrons from protons (10 - 12 = -2) you get the charge.
The charge would be 1+, as there is an overall single positive charge, due to the fact that there is one more proton than electrons.
The number of neutrons is irrelevant, so concentrate on numbers of electrons and protons. There is one more electron, therefore there must be an overall negative charge of 1-.
-1 or negative one
-1

mmmm
sodium's atomic number is 11 and since protons and electrons are the same number as the atomic number, there are 11 protons and 11 electrons, to get the neutrons you take the isotope of sodium you are given, in this case 23 and subtact the number of protons, so 23-11=12. Therefore there are 12 electrons.
Sodium has 11 protons, 11 electrons and 12 neutrons.
Atomic # : 12 Mass Number : 24 # of Protons : 12 #of Neutrons : 12 # of Electrons : 12
elecrons - 11 neutrons - 12 protons - 11
none because the number of protons and electrons have to be the same.
Electrons~ 11 Neutrons~11 12Protons~11Youre welcome(;___________________________ (Improved answer) No, It has 11 electrons, 11 protons and 12 neutrons.
An atom with 11 protons, 12 neutrons, and 11 electrons. B. An atom with 11 protons, 10 neutrons, and 11 electrons.An atom with 11 protons, 12 neutrons, and 11 electrons.
Na has 11 protons and 12 neutrons and 11 electrons.

(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
12 + 10 = 22 charge
12 + 10 = 22 charge
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
Sodium has 11 protons, 11 electrons and 12 neutrons.
Not necessarily, the number of protons in an atom are exactly the same as the electrons in an atom. For example, sodium has 11 protons and 12 neutrons. How many electrons does it have? 11.
