protons and electrons are equally charged except that protons are positively charged and electrons are negatively charged, as there are more protons in this example there is a positive net charge
Group 17A, also known as Group 7A has a charge of -1
1-
-1 ion
What charge would you find on a Group 2 ion?
Potassium is a group 1 element, so it will form a 1+ ion.
A polyatomic ion is a group of atoms with a charge.
17
A chloride ion (of the isotope 35Cl) with a charge of -1. The 17 protons tell you its chlorine and since there is one more electron than proton it has a charge.
17
1
because chlorine has 17 protons contributing to a +17 charge, 18 electrons have a -18 charge, 17-18 = -1 which is the overall charge of the ion
An ion is an atom (or group of atoms) with an electrical charge.
Sodium is in group one, chlorine in group 7. This means that a Sodium ion has a charge of +1, and a Chlorine ion has a charge of -1.
What charge would you find on a Group 2 ion?
The halogens, listed in column 17 of a wide form periodic table.
-1
A bromine ion has a -1 charge. That's because it is a halogen, and it is an electron "borrower" which wants to steal an electron to "complete" its outer electron shell. When it snags an electron to fulfill that tendancy of atoms to attain inert gas electron configuration, it ends up with that "extra" electron and a -1 charge. This is typical of all halogens, those elements that make up the Group 17 elements.
Potassium is a group 1 element, so it will form a 1+ ion.
The chlorine ion is in group 7 so it has a charge of -1.
A polyatomic ion is a group of atoms with a charge.
