For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
strontium is a metal, therefore it must form only positive ions.
Lead can form ions with a charge of +2 or +4.
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.
Sulfur monoxide is a gaseous compound, NOT an ion; hence it has NO charge.
The charge of an NO ion is -1. This is because nitrogen typically has a charge of +5 and oxygen typically has a charge of -2, resulting in a charge of -1 for the NO ion.
strontium is a metal, therefore it must form only positive ions.
The ion charge on sulfate is 2-. This means that the sulfate ion carries a charge of -2.
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
loses 2 electrons to form a calcium ion with 2+ charge
The charge is minus 2.
Lead can form ions with a charge of +2 or +4.
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.
the charge of zinc has only one charge which is 2+.
Sulfur monoxide is a gaseous compound, NOT an ion; hence it has NO charge.
Elements in Group 2 of the periodic table form ions with a charge of 2. This group includes elements such as calcium, magnesium, and barium. When these elements lose two electrons, they form ions with a +2 charge.
The charge of an NO ion is -1. This is because nitrogen typically has a charge of +5 and oxygen typically has a charge of -2, resulting in a charge of -1 for the NO ion.
Iron can acquire a charge of +2 or +3 as an ion. The +2 charge is more common and is known as ferrous ion, while the +3 charge is less common and is known as ferric ion.
