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?

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?
