what is the total number of electrons for magnesium?
1003
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. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and two more in shell three.

Aluminum is in the fifth column and therefore has 5 electrons in its outermost shell. It would tend to lose three electrons and form a +3 ion. Magnesium is in the second column and therefore has 2 electrons in its outermost shell.

Atomic number is the total number of electrons. The valence electrons are only those in the outer shell.

Magnesium is in Group 2. It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2+, is formed. A magnesium ion has the same electronic structure as a neon atom (Ne).
1254332
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. The atomic number is always the same for any atom.

The answer is 1.75 x 10^51. The answer is 1.75 x 10^51. The simplest way to determine this is to calculate the number of protons in the earth. The number of electrons will be equivalent to the number of protons.

Ag+ = 47 electrons - 1 electron = 46 electrons. Finally: 47 protons , 61 neutrons and 46 electrons.

Yes, the Mg2+ ion and the neutral neon atom are isoelectronic, which implies that they have the same number of electrons and, of course, the same electron configuration. Magnesium has an atomic number of 12, which means its neutral atom has 12 electrons.

There are 10 electrons in a Mg2+ ion. A neutral atom of magnesium would have 12 electrons to balance out the positive charge of the 12...

Mg-26 has 12 protons and 12 electrons when neutral. How many neutrons does it have?

The M shell only holds eight electrons. The M shell can actually hold up to 18 electrons as you move to higher atomic numbers.

You can calculate \(F\) by multiplying the charge on one electron (1.602 x 10-19) by Avogadro's number (6.022 x 1023). For this reaction, we would say the number of electrons, \(n\), is two. For every mole of zinc that reacts, it produces two moles of electrons.

Oxygen gains two electrons to have an octet. The ionic bond between ions results from the electrostatic attraction of opposite charges. The final formula of magnesium oxide is MgO.

For instance, 24Mg is read as “magnesium 24,” and can be written as “magnesium-24” or “Mg-24.” 25Mg is read as “magnesium 25,” and can be written as “magnesium-25” or “Mg-25.” All magnesium atoms have 12 protons in their nucleus.

Take the total charge... 2.2*10^7C... and divide by charge/electron = 1.6*10^-19C/electron. That gives you the number of electrons.

The L shell only holds eight electrons. The M shell only holds eight electrons. The M shell can actually hold up to 18 electrons as you move to higher atomic numbers. The maximum number of electrons you will find in any shell is 32.
