S
Te or Tellurium
Argon
A certain element forms an ion with 10 electrons and a charge of +2. Identify the element
Cadmium forms ion with +2 charge. It is Cd2+
As an element oxygen is neutral, but it forms negative ions.
Oxygen
Te or Tellurium
Calcium
It forms an octet / stable electronic configuration
Beryllim is an element. It forms a Cation that has a 2+ charge, because it must lose electrons to gain a noble gas configuration. Anions gain electrons which would have a negative charge.
Argon
A certain element forms an ion with 10 electrons and a charge of +2. Identify the element
potassium
Cadmium forms ion with +2 charge. It is Cd2+
Promethium is an element and does not have a charge. As it has only be found in trace quantities, its chemistry has not been fully investigated. It has been anticipated that the likely charge when it forms compounds would be +3.
sulfur
As an element oxygen is neutral, but it forms negative ions.
