Arsenic must gain 3 electrons to become the As-3 ion.
The arsenic iii ion is oxidised to arsenic V ion and iodine is reduced to iodide.
There are 33 electrons in an Arsenic atom.
A sodium atom would lose a electron so it would become a Na+ ion
Its charge lose an negative charge. So it is positively charged. +1
The neutral atom become an ion (cation) with the charge +1.
As2-
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
Helium is a neutral atom that has several isotopes and can become an ion.
The ion given is formed when the neutral arsenic atom gains three electrons.
An ION. Ions are divided into two classes. CATIONS ;positive ions e.g. Na^(+) ANIONS ; negative ions e.g Cl^(-)
When an atom loses a negative charge, when it loses an electron, it becomes a positive ion.
it becomes an ion
An atom of Calcium will lose an electron to become a posotive ion.
IONS OS ION ^^A charged atom is called an ion
An atom looses or gains electron to become ion. Ions are +ve and -ve atoms.
The arsenic iii ion is oxidised to arsenic V ion and iodine is reduced to iodide.
It will become a soft ion.
