What is the ionic charge for selenide?

What is the ionic charge for selenide?

2-

What is the name for Ag2Se?

Silver selenide

How many electrons are in a selenide ion?

36 electrons

Does selenium form a positive ion?

It has six electrons in the valence shell. If it gains two electrons, its octet will get complete. Thus, when selenium forms an ion, the ionic charge will be -2 after gaining two electrons and the selenium ion is Se2−.

How does selenium become an ion?

Selenium (Se) has an atomic number, and belongs to group 6A. So it will have 6 valence electrons. When two electrons are gained by selenium atom, it forms an anion having charge of -2.

N3− nitride ion

What is the difference between magnesium and magnesium ion?

Answer. Magnesium ion has 10 electrons while magnesium atom has 12 electrons. Magnesium ion is neutral while magnesium atom is positively charged.

Why is a magnesium ion smaller than a magnesium atom?

The magnesium ion is much smaller than the magnesium atom because magnesium atom contains more electrons as compared to magnesium ion. Explanation: Whereas when an atom tends to lose an electron then it acquires a positive charge and size of the atom tends to increase.

What type of ion does magnesium form?

Magnesium is in the second column and therefore has 2 electrons in its outermost shell. It would tend to lose two electrons and form a +2 ion. Potassium is in the first column and therefore has 1 electron in its outermost shell. It would tend to lose one electron and form a +1 ion.
