In a neutral compound, the sum of charges of all cations and anions will be zero. This is because cations have a positive charge and anions have a negative charge, and in a neutral compound, these charges will balance out.
Cations and anions
The arrangement of cations and anions in a compound depends on the charge of the ions and the overall stoichiometry of the compound. The goal is to achieve electrical neutrality by balancing the positive and negative charges. This often results in a specific crystal lattice structure being formed.
No, barium hydroxide is an ionic compound, not a covalent compound. It is composed of barium cations and hydroxide anions, which are held together by ionic bonds formed through the transfer of electrons.
Yes, manganese stearate is an ionic compound. It consists of manganese cations and stearate anions held together by ionic bonds.
