The ionic symbol with 4 protons and 2 electrons is Be2+, which represents the beryllium ion. Beryllium normally has 4 protons and 4 electrons, but when it loses 2 electrons to become stable, it forms the Be2+ ion.

What is the symbol of an ion with 50 protons 68 neutrons and 48 electrons?

The symbol of an ion is determined by the number of protons and electrons. With 50 protons and 48 electrons, this ion has a +2 charge (50 protons - 48 electrons = +2 charge). Therefore, the symbol would be written as Sn2+.


What is the symbol for 2 electrons and 2 protons?

Number protons equal to atomic number. So the element is Helium


What is the symbol for the ion with 22 protons and 24 electrons?

Ti2- would be the symbol for an ion with 22 protons and 24 electrons. This would be EXTREMELY unlikely to exist though. Ti2+ is more usual with 22 protons and 20 electrons. Ti4+ is even more stable with 22 protons and 18 electrons.


Ion symbol for 16 protons and 18 electrons?

Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .


If an ion has 26 protons and 24 electrons what is the ionic charge?

+2: 26 - 24.


What is the chemical symbol for the ion with 33 protons and 36 electrons?

The chemical symbol for the ion with 33 protons and 36 electrons is As3-. This ion has a charge of -3, which means it has gained 3 electrons compared to its number of protons.


How do you write the charge of an ion?

find the difference between the number of electrons and protons, and then find whether protons(+) or electrons(-) are more abundant. if the difference was 2, for example, and there were (2) more protons than electrons, the charge would be written as: chemical symbol 2+


What is the symbol of alpha radiation?

The alpha particle is a helium nucleus. Its symbol is 24He2+, meaning 2 protons, 2 neutrons, and no electrons.


What is calcium ionic symbol?

The ionic symbol for calcium is Ca^2+. It indicates that calcium has lost two electrons to achieve a stable electron configuration in its outer shell.


What is the symbol for an ion with 16 protons 16 neutrons and 18 electrons?

S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.


What the chemical symbol for the ion with 12 protons and 10 electrons?

Magnesium, with a +2 charge.


What is the chemical symbol for ion with 31 protons 39 neutrons and 28 electrons?

The chemical symbol for an ion with 31 protons, 39 neutrons, and 28 electrons is ^70Ga3+. This represents gallium with a charge of +3 due to the loss of 3 electrons.
