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)
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.
A barium ion is denoted as Ba^2+.
The formula for barium (Ba) combined with carbonate (CO3) is BaCO3. In this compound, barium has a charge of +2, while the carbonate ion has a charge of -2, which balances out to form a neutral compound. Thus, one barium ion pairs with one carbonate ion to create barium carbonate.
Barium (Ba) will typically have a +2 charge as it is a group 2A element.
The Stock name for the chromium ion with a 3 plus charge is chromium(III). In this naming system, the Roman numeral indicates the oxidation state of the metal ion. Thus, chromium(III) signifies that chromium has lost three electrons to form the ion.
Barium ion = Ba2+ Hydroxide ion = OH-
When barium ion is added to a hydroxide ion, the two opposite charges attract each other to form barium hydroxide Ba2+ + OH------>Ba(OH)2.
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.
Ba looses its two electrons to form Ba 2+ ion and then it reacts with other elements to form compounds.
I believe that would be Barium nitrate or Ba(NO3)2
Barium is +2 valenced ion, so its oxidation state is +2 in ion form (Ba2+) and 0 in elemental (Ba) 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
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
The cation of barium is Ba(2+).
