yes, Barium is unlikely to form positively charged ions.
positively
barium choride and calcium sulphate will form
Unless they are ions, atoms are neutrally charged. The negatively charged electrons orbitting the nucleus neutralized the positive charges of the protons in the nucleus. neutrons do not have an electrical charge. ions are the exception to this, as they have either added or removed orbitting electrons. if an atom has electrons removed, then it is a positively charged cation. most metals form positively charged ions. if electrons are added, then it is a negatively charged anion. most non-metals form negatively charged ions.
Barium can form two distinct compounds with oxygen as the only other element in the compound: barium oxide with formula BaO and barium peroxide with formula BaO2. The first of these compounds is more common and more stable.
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
selenium
No, potassium, as a metal, very easily forms a positive ion.
positive
it's a simultanious attraction between a positively charged ion and a negatively charged ion it's a simultanious attraction between a positively charged ion and a negatively charged ion
Metals for positively charged ions and nonmetals form negatively charged ions.
hydrogen bonds
Mn2+. Cations are positively charged anions are negative. Metals such as Mn manganese form positively charged ions, cations , when they transfer electrons to non metals such as iodine I.
Atoms lose electrons to form positively charged cations.
They are composed of positive and negative ions.
Yes and No, because Barium has two valence electrons and Bromine has 7, which would add up to 9 valence electrons when you can only have 8 if you want to be positively charged, so naturally they would not bond with each other. If they did end up bonding somehow, they would be negatively charged with 1 valence electron and only then could that be bonded with another Bromine atom.
an electrical charge, otherwise known as lightning during a thunderstorm
No, ionic bonds form between particles with opposite charges.
