You have an ion with a positive or negative charge.
Ex.: [H+] is a positive hydrogen ion waiting to accept another atom to form a compound with.
They have not atomic numbers. Atomic number is made by number of protons an atom has.
A proton. A proton has a mass of 1 a.m.u. while an electron has a mass of 1/1840 a.m.u.
A proton has a positive charge which is equal in magnitude but opposite to the charge on an electron, which is negative.
Magnesium (Mg) Bottom number is the proton number. Top number is mass number = Protons + Neutrons Therefore no. of neutrons = Top - Bottom number In atom proton number = electron number. However if it was an ion of Mg e.g. Mg+ then its electron number would be 13 and its proton number would be 12. Hope this will help. P.S I gave you the extra info as you will now be able to work out WHY! :D
There is no such thing as a proton volt.
When the proton number and electron number are unequal, the atom or molecule becomes an ion. If there are more protons than electrons, it becomes a positively charged cation. If there are more electrons than protons, it becomes a negatively charged anion.
Number of Proton(or Electron) in the Atom
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
Atomic number = Number of protons = Number of electrons
because an atom is electrically neutral
neutral
the number of proton neutron and electron proton(+p) and electron(-e) has 78 and neutron has 116, 117, or 118 (or from 112 to 120, including synthetic isotopes)
Neutron, proton, electron.Neutron, proton, electron.Neutron, proton, electron.Neutron, proton, electron.
An electron will not decay into a proton by any means.
A proton is bigger than electron
A proton is bigger than electron
