Answer:
1 proton , 1 electron ,0 neutron
Explanation:
neutrons 4
yes
The number of elections, protons an neutrons in a species are equal to 18,16,16 respectively. Assign proper symbol to the species.
atomic number is equal to number of protons =16. The element is sulphur mass number is equal to number of protons plus number of neutrons 16+16=32 . Since the number of protons is not equal to number of electrons therefore the species is not neutral it is anion (negatively charged)it has -2 charge on it symbol =S^minus 2
Neutrons of Mg2+ is 12.Electrons 10.find mass,atomic number ,protons.
Mg2+ ion is formed by loss of two electrons by Mg atom.
Therefore, it has two electrons less than the number of electrons in Mg atom.
Mg2+ = Mg – 2e
Number of electrons = 12-2 = 10
Number of protons = 12
Number of neutrons = (24- 12) = 12.
Therefore, it has two electrons less than the number of electrons in Mg atom.
Mg2+ = Mg – 2e
Number of electrons = 12-2 = 10
Number of protons = 12
Number of neutrons = (24- 12) = 12.
atomic number=12
mass 24
