How many protons electrons and neutrons are present in a hydrogen ion?

Hydrogen is a funny critter. It always has one proton, and it usually has no neutrons. But rarely it can have one neutron, and even more rarely, it can have two neutrons. There is more. Hydrogen can appear either as just the proton having loaned out its electron to become a positive ion (H+), or it can at times borrow an electron and become a negative ion (H-). That means the ion might have two electrons, but usually it has no electrons.


A hydrogen atom which has lost an electron contains?

After it has lost an electron, a hydrogen ion contains one proton and a variable number of neutrons depending on the isotope (usually none).


What is hydrogen's number of neutrons equals mass number - atomic number equals?

The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).


What is the atomic number number of neutrons and the number of electrons of hydrogen?

Normal Hydrogen has an atomic number of 1, no neutrons and 1 electron.


What is the ion charge number of Hydrogen?

The ion charge number of hydrogen is +1.


How many neutrons are in the nucleus of an atom hydrogen?

With no electrons, as a bare nucleus, it exists as the H+ ion. Hydrogen can have any number of neutrons and still be hydrogen. H-1 (0 neutrons) is the most abundant isotope in nature. H-2(1 neutron) has the special name of deuterium and is stable and found in nature.


Isotopes of hydrogen differ in what?

Isotopes (of hydrogen) differ in the number of neutrons in the nucleus of the atoms.


How many neutrons does an mg2 ion have?

An Mg2+ ion is a magnesium ion that has a charge of +2, meaning it has lost 2 electrons. The number of neutrons in an Mg2+ ion is the same as in a regular magnesium atom, which is 12 neutrons.


What ion has 52 protons 76 neutrons and 54 electrons?

The ion with 52 protons, 76 neutrons, and 54 electrons is the ion of element tellurium (Te) with a charge of +2. The number of protons determines the element, the number of neutrons can vary in isotopes, and the number of electrons determines the charge of the ion.


What element has one proton and zero neutrons?

Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.


The number of neutrons that hydrogen has?

Hydrogen has no neutrons. It has 1 proton in the nucleus and 1 orbital electron.


How can you tell if an atom is an ion?

If the number of protons and neutrons are the same, its an atom, if not its an ion
