how many protons and electrons does the most stable ion for magnesium have?

(a) Magnesium has atomic number 12, so all atoms of magnesium contain 12 protons and 12 electrons. The three isotopes are therefore represented by Mg, Mg, and Mg. (b) The number of neutrons in each isotope is the mass number minus the number of protons.

Copper has an atomic number of 29, so it contains 29 protons and 29 electrons. The atomic weight (sometimes called atomic mass) of an atom is approximated by the sum of the number of protons and the number of neutrons in the nucleus of the atom.

An ion is formed by the loss or gain of electrons by an atom, so it contains an unequal number of electrons and protons. Example: Sodium ion Na+, magnesium ion Mg2+, chloride ion Cl–, and oxide ion O2–. There are two types of ions : cations.

The Zn2+ ion has lost two electrons, which leaves it with 30 protons and 28 electrons. The electron configuration of Zn2+ is 1s22s22p63s23p63d10 .

Do ions have valency? - Quora. Ions can still have valence electrons. The more obvious ions are stable at a noble gas configuration, but there are often elements that can lose (or gain) different numbers of electrons in forming ions. For example magnesium can lose one or two electrons.

The charge of an aluminum ion is typically 3+. This is because the element's atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons.

Sulfur, which only needs two electrons to complete it octet, will pick up the two electrons coming from magnesium, becoming the sulfide anion, S2− , in the process. The electrostatic force of attraction will then bring the magnesium cations and the sulfur anions together → an ionic bond is formed.

As you can see, magnesium oxide contains the most elemental magnesium of 60%. And 23% of this can be absorbed. Magnesium citrate, for example, contains only 11% elemental magnesium. And only 30% of this is absorbed.

When Mg is Mg2+ it loses 2 electrons from the valence shell. That means it has only 10 electrons. Atomic number is 12 meaning there are 12 protons and electrons.

if an atom of an element is electronically neutral then the number of protons (atomic number) will be equal to the number of electrons. Therefore Magnesium atom has 2 valence electrons, which explains why it likes to form Mg2+ cations by losing the latter 2 electrons.

So... for the element of MAGNESIUM, you already know that the atomic number tells you the number of electrons. That means there are 12 electrons in a magnesium atom.

A potassium ion, K+ has an atomic number of 19 and a mass number of 39 So there are 19 protons and 39-19 = 20 neutrons. To become a positive ion it looses its valence electron with its valence shell and becomes K+ by achieving the configuration of 2,8,8,1 with 3 energy levels/shells.

Magnesium and fluorine combine to form an ionic compound. What is the formula for the compound? Mg most commonly forms a 2+ ion. This is because Mg has two valence electrons and it would like to get rid of those two ions to obey the octet rule.
