Question

Oxide Ion and Magnesium Ion

Answer 1

It actually depends on the ion, how many electrons have been stripped away.

Answer 2

O-- and Mg++

In the Periodic Table, the atomic number is the number of protons in the nucleus. In neutral atoms (not ionized), the number of electrons equals the number of protons. The atomic mass represents the mass of protons, neutrons and electrons. Although the atomic mass values in the periodic table are average values across whatever isotopes are present and include a small contribution from binding energy, you can get a good idea of the number of neutrons in an element by subtracting its atomic number from its atomic mass. To understand this better, see the Wikipedia on atomic mass:

With the above information you can easily calculate the number of protons, electrons and neutrons in O-- and Mg++ respectively as 8,10, 8 and 12,10,12

Answer 3

You can easily find it in books and search engines.

Answer 4

look on the periodic table..

Answer 5

The protons and electron parts are easy.



Oxide, O^2-, has 8 protons (that&#039;s what makes it oxygen) and since it has a -2 charge, it has gained two electrons, so instead of 8 electrons (neutral atom) it will have 10 electrons.

Magnesium ion, Mg^2+, has 12 protons and 12 electrons in the neutral atom, but since it has lost two electrons it will have 10 electrons.

O2- and Mg2+ are isoelectronic.  That means they have the same number of electrons.

There is no way to say exactly how many neutrons each has because oxygen and magnesium each have three stable isotopes.  The number of neutrons is different for each isotope.
