What is the number of valence electrons and oxidation number of strontium?

The oxidation number is the number of valence electrons. The valence electrons are the electrons on the outermost energy level.

Argon's valence number is 8, it has 18 electrons, and its oxidation number is 0 because it doesn't react.

If its positive it tells u that it has that number of valence electrons. If negative it tells you that it requires that number of electrons to make the valence electrons filled up/stable. If you know which Ion it is, you know the number of valence electrons of the neutral Atom. It corresponds to the group in the periodic table, the element is in. For example: Mg. It's in group 2, so it has 2…

Well, the oxidation number is the number it takes to get to either 0 valence electrons or 8 valence electrons. Say we had the atom...Hydrogen. It has 1 valence electron, so it only take 1 to get to zero. Therefore, the oxidation number would be +1.

In an atom of an element has one or two valence electrons and is not a helium atom, the most likely oxidation state is positive by the number of valence electrons, while if the atom of an element has seven or six electrons, the most likely oxidation state is negative by the number of electrons required to total eight valence electrons. Helium and all the atoms with eight valence electrons have a most likely oxidation…

Boron has an oxidation number of +3. It will try to lose the three valence electrons that it has, so that it is stable. Electrons are negative, and removing them would make the oxidation number positive.

Sulphur has 6 valence electrons. So its maximum oxidation number is +6.

Nitrogen has an oxidation number of -3. Since it is in group 15, it has 5 valence electrons. It wants to have eight, so it will gain three electrons. Electrons are negative, that's why the oxidation number is negative.

Bromine has an oxidation number of -1. Since it is in group 17, it has seven valence electrons. It wants to have eight, so it will gain an electron. Electrons are negative, that's why the oxidation number is negative.

The oxidation state is the difference between 8 and the number of valnce electrons, excepting transition metals.

The oxidation number of F, or Fluorine, is F-1. Since it is in the seventh group on the periodic table, it has seven valence electrons. It needs to get eight valence electrons to be stable, so it will gain one electron.

The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.

Bromine is in the seventh family on the periodic table. That means that it has seven valence electrons. It wants to have eight valence electrons to be stable, so it will gain an electron, making it negative. The oxidation number of Br is Br-1.

Arsenic has an oxidation number of -3. Since it is in group 15, it has five valence electrons. It wants to have eight, so it will gain three electron. Electrons are negative, that's why the oxidation number is negative.

A strontium atom differs from a strontium ion in that the atom has a greater number of electrons Explanation: Strontium has 2 valence electrons in its outer shell. It is easier to lose these 2 electrons than it is to gain 6 more electrons. Losing 2 electrons will give the strontium ion a charge of +2. Ions are charged atoms. An neutral atom has no charge because it has the same number of protons and…
