I would guess it is because it is the most reactive so it is the hardest to reduce.
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
The ionic compound formed between barium and sulfur is barium sulfide, which has the chemical formula BaS. Barium is a group 2 metal with a 2+ charge, and sulfur is a group 16 nonmetal with a 2- charge. Therefore, to balance the charges, one barium ion (Ba2+) combines with one sulfide ion (S2-) to form BaS.
Ah, what a lovely question! In period 6, the element in the same group as Magnesium (Mg) is Barium (Ba). Both of these elements share similar chemical properties due to being in the same group on the periodic table. Isn't it fascinating how elements can show such wonderful patterns and relationships?
The barium ion has the formula Ba2+, and the Sulphide ion has the formula S2-. The formula for the formation of Barium Sulphide is: Ba + S --> BaSThe formula for Barium Sulphide is BaS
Valence electrons are electrons that are on the outside "shell." In Group (column) 1, there is only one valence electrons for each element. In Group (column) 2, there are two valence electrons. Group 13: 3 valence electrons Group 14: 4 valence electrons Group 15: 5 valence electrons Group 16: 6 valence electrons Group 17: 7 valence electrons Group 18: 8 valence electrons There is no Group 19, so this list is done. For the metals, each element will need to be mapped out utilizing the Bohr Diagram design or something of the like as valence electrons are difficult to define due to the grouping on the periodic table. The most valence electrons that can be in an outer shell is eight. Barium (Ba) is in Group (column) 2, and thus has only two valence electrons.
Barium is an element, not a mineral.
Barium is a metal. It belongs to group 2 or alkali metals
No. Barium and magnesium and calcium are in group 2A but potassium is in group 1A.

Barium is a metal. It belongs to group 2 or alkaline earth metal
Barium is located in the alkali metals group.
Barium Is In The 2nd Group Other Wise (The Alkali Earth Metals Group) & It Will Be The 5th One Down.
Barium is more reactive than magnesium, and beryllium is less reactive than both. Reactivity generally increases as you move down a group on the periodic table, so barium is more reactive than magnesium due to its position in the same group.
Barium is alkaline earth metal. It belongs to group-2.
This is because Barium has 2 valence electrons, which gives it group 2, and because it has 6 energy leves which puts it in group 6.
Barium is not a metal; it is an alkaline earth metal found in Group 2 of the periodic table.
Barium belongs to Group 2, so there are 2 valence electrons
