How many valance electrons are transferred from the calcium atom to iodine in the formation of calcium iodide?

A calcium atom will transfer its two valence electrons to two separate iodine atoms in the formation of calcium iodide. The calcium atom becomes a Ca2+ ion, and each iodine atom becomes a 1- iodide ion. The electrostatic force of attraction between the oppositely charged ions forms ionic bonds between the ions.Ca + I2 --> Ca + I + I --> Ca2+ + I- + I- --> CaI2Overall reaction:Ca + I2 ---> CaI2

What does a calcium atom become when it loses 2 electrons?

When a calcium atom loses two electrons, it is still a calcium atom. However, the charge goes up by 2.

What scientific element has 20 electrons?

Calcium has twenty electrons in each atom.

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.

Lewis structure of calcium nitride?

Ca3N2 has a Lewis structure that starts with a Calcium atom in the center. From this Ca atom, there are two single bonds, each connected to a Nitrogen atom. Each nitrogen atom then has a double bond with a single Calcium atom.

How many valence elections are transferred from the calcium atom to iodine in the formation of the compound calcium iodine?

One calcium atom will transfer one of each of its two valence electrons to one each of two iodine atoms. In the process, the calcium atom becomes a calcium ion with a 2+ charge, and each iodine atom becomes an iodide ion with a 1- charge. The opposite charges between the iodide and calcium ions form an electrostatic attraction called an ionic bond, forming the ionic compound calcium iodide. Ca + I2 ---> I- + Ca2+ + I- ---> CaI2
