Astatine is in the group 7A of the Periodic Table. The members of this group all have an ionic charge of -1, so At (astatine) will have a -1 ionic charge.
Mostly -1, but +1, +3, +5 and +7 are also found.
Mostly -1, but +1, +3, +5 and +7 are also found.
This compound is of course neutral.
Atoms carry a positive charge on the proton and a negative charge on the electron, usually these cancel out.
When halogens form ions, they are called halide ions. These types of ions have a negative charge due to gaining electrons.
Magnesium ions have a charge of 2+ and will react with negative ions to form ionic compounds with an overall charge of 0.
Mostly -1, but +1, +3, +5 and +7 are also found.
Since astatine is a group 7 element I guess it is -1.
On their own metals have no charge. Metal ions have a positive charge.
This compound is of course neutral.
A crystal of salt consists of electrons and positive ions. How does the net charge of the electrons compare with the net charge of the ions
Calcium ions have a charge of plus two, and bromine ions have a charge of minus one.
Plus charge, ie, it has H3O^+ ions (hydronium ions)

false
Hydrogen ions are H+Hydroxide ions are OH-neutrons are written n and have no chargeelectrons are written e- and have a negative charge.So only hydrogen ions, H+, has a positive charge.
