Question

When an atom of lithium loses an electron, the atom becomes a

1. negative ion with a radius smaller than the radius of the atom
2. negative ion with a radius larger than the radius of the atom
3. positive ion with a radius smaller than the radius of the atom
4. positive ion with a radius larger than the radius of the atom

Answer 1

3

Step-by-step explanation:

Answer 2

An electron has a negative charge. When an atom loses an electron, it becomes a positive ion.
When an atom of lithium loses an electron and becomes an ion, it has one less electron shell, so its radius is smaller than the radius of the atom.
The answer is 3.
