What is the most common charge of barium?
Ba has no charge overall but the Barium ion has a 2+ charge.
Why does a Ba form a plus 2 ion?
In the periodic table, Ba is in the 2nd group, making it have a charge of 2 and it is a metal so it's a cation, making it lose electrons(+) so its charge would be Ba2+. (2+ is a superscript)
Why do you put parentheses around a polyatomic ion?
You use parentheses to represent that a polyatomic ion is used more than once as a whole. For example Ba(NO2)2. It is NO2 that is used twice because Ba has a 2+ charge and NO2 has a -1 charge. So you need 2 NO2 to make the formula equal 0. So you use the parentheses to represent you are using 2 NO2
What charge is present on an atom when it gains 2 electrons?
When an atom loses two electrons it becomes +2, as Mg, Ca, Ba.
What is the difference between Ba and Ba 2 plus?
Ba2+ is the ion of the Ba atom. That means it has given away two electrons to other atoms in order to reach a stable state with 8 electrons in its outer shell.
What is the most common charge of barium?
Ba has no charge overall but the Barium ion has a 2+ charge.
What charge do group 2 metal ion carry?
What charge would you find on a Group 2 ion?

What is the formula ion formed from Ba?
The cation of barium is Ba(2+).

What is An ion with a positive electrical charge?
Such ions are called cations. They are usually individual metal atoms that have lost one or more electrons from their outermost shell. This loss of electrons (and thus a loss of negative charge) produces a slight positive charge on the remaining ion, e.g Li+, Rb+, Mg++, Ba++, Fe++, Fe+++. Notice that all of these ions are atoms from the metal section of the Periodic table, the centre, the lower, and the left hand Such ions are called cations.

Barium BA is in Group 2 Recall that atoms in Group 1 lose one electron to form ions with a 1 charge What type of ion does barium probably form?
barium will lose two electrons to form an ion with a plus 2 charge. Thus, the resulting ion in reactions of barium is Ba2+.Read more: http://wiki.answers.com/What_type_of_ion_would_barium_form_if_group_1_loses_one_electron_to_form_ions_with_a_1_plus_charge#ixzz17vdoXVSf
What is the formula for the compound formed by the barium ion Ba2 plus and the hydroxide ion OH NEGATIVE?
When combining atoms or groups to form a compound, look at their charges to determine how many of each you need in order for the positive and negative charges to cancel out (form a neural compound). Since Ba has a +2 charge and OH has a -1 charge, you need two OH groups to cancel out one Ba atom. In other words, make it so that +2 + -2 = 0. Here's the overall equation:Ba2+ + 2OH- --> Ba(OH)2
What ion has 53 protons and 54 electrons?
Ba
When a barium atom forms its most common ion it?
Ba^2+
Chemical symbol for the most stable ion of barium?
Ba^2+
What is the formula for barium ion and hydroxide ion?
Barium ion = Ba2+ Hydroxide ion = OH- The compound they make is Barium hydroxide = Ba(OH)2which is a precipitate insoluble in water.
