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.

Why does proton and electron are equal atomic number?
They have not atomic numbers. Atomic number is made by number of protons an atom has.
Which has a bigger mass proton or electron?
A proton. A proton has a mass of 1 a.m.u. while an electron has a mass of 1/1840 a.m.u.
What is the electric charge does proton have in electron?
A proton has a positive charge which is equal in magnitude but opposite to the charge on an electron, which is negative.
What element has 12 electrons and 12 protons?
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
How would a proton volt compare with an electron volt?
There is no such thing as a proton volt.
When the proton number and electron number are unequal the atom or molecule what?
has a charge which can be positive (excess protons) or negative (excess electrons). ... becomes an ion - positive ion if deficient in electrons, negative with an excess of electrons.
What does the atomic number indiacate?
Number of Proton(or Electron) in the Atom
What is the formula for the atomic number?
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
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
What no. ef proton and electron in an atom?
Atomic number = Number of protons = Number of electrons
What are the number of protrons and electrons for magnesium ion?
the number of proton=the number of electron= 12
Why number of electron are equal to the number of proton?
because an atom is electrically neutral
The ion that is a single proton?
H-1. Hydrogen has only one proton and electron; if this electron is removed a hydrogen ion is formed - effectively a proton.
What are three subatomic paarticles in an atom?
Neutron, proton, electron.Neutron, proton, electron.Neutron, proton, electron.Neutron, proton, electron.
Where there is the same number of proton's as electron's the charge on the atom is considered?
neutral
How big is a electron compared to a proton?
A proton is bigger than electron
How big is a proton compared to a electron?
A proton is bigger than electron
