Which has a larger radius calcium atom or a calcium ion?

Calcium atom.

In terms of electrons why is the radius of a calcium ion smaller than the radius of a calcium atom?

A calcium ion is Ca2+ and has 18 electrons and 20 protons. A calcium atom is Ca and has 20 electrons and 20 protons. So the ion has the same number of protons pulling a smaller number of electrons closer to the nucleus and so the ion is smaller.

When a calcium atom becomes an ion it does what?

A calcium atom becomes a calcium ion by losing two electrons, forming a Ca2+ ion.

Is Ca2 plus a atom?

No. Ca2+ is a calcium ion.

To form an ion what does a calcium atom gain or loose?

An atom of Calcium will lose an electron to become a posotive ion.

How does the radius of a positive and negative ion compare to a neutral atom?

For the positive ion the radius is smaller; for the negative ion the radius is bigger.

Which element forms the ion with the largest radius?

tellerium (Te) has the largest radius

What is the name of the ion formed by a calcium atom?

caltribadium ion

What is the difference between the size of the radious of a positive ion to its neutral atom?

The radius of a positive ion is less than the radius of an atom from which it can be derived.

What happens to the electrons of a neutral calcium atom when it is changed into a calcium ion?

it becomes a positive ion

Is calcium an ion?

Calcium is an element. It is most commonly found as an ion, but can exist as a normal atom.

Why the radius of an atom larger than the radius a positive ion formed from it?

The positive ion lost an electron.
