I think it's negaive
The strontium ion is positive, divalent, Sr2+.
Strontium.
Strontium form the divalent cation Sr2+.
The same as the positive ones with negative signs.
Sr(NO3)2 Since strontium ion (Sr2+) has a charge of +2 and nitrate ion (NO3-) has a charge of -1, there must be 2 nitrates to account for 1 strontium making the formula neutral
The strontium ion is positive, divalent, Sr2+.
I think it's negaive
Na is positive ion,Cl is negative ion
strontium is a metal, therefore it must form only positive ions.
it is a negative and positve ion sweg
An ion is either a positive charged or a negative charged atom. Negative ions have one or more extra electrons, and positive ones have one or more electrons not there.
An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.
To become more stable: positive+negative=neutral. Neutral is more stable than positive and/or negative.
Zinc ion (cation) is positive.
negative
when an atom loose electron it become negative ion and when it gains electron it become positive ion
The strontium ion is called the Sr2+ ion. It has a 2+ charge due to the loss of two electrons from a neutral strontium atom.
