How many valance electrons are transferred from the calcium atom to iodine in the formation of calcium iodide?
Wiki User
∙ 12y ago
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- --> CaI2
Overall reaction:
Ca + I2 ---> CaI2

What is the valance electrons in calcium?
2
Which particles of the atom participate in the formation of chemical bonds?
electrons. More specifically, valance electrons
What is the highest occupied energy level of Ba?
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.
What makes a covalent bond different from an ionic bond?
With a covalent bond, atomic nuclei are sharing some of their valance electrons, which means that the electrons are in orbit around both (or all of) the nuclei in question. With an ionic bond, valance electrons are transferred from one atom to another. Once transferred, the electrons orbit only around the atomic nucleus that has received them.
What are the electrons involved in the formation of a chemical bond called?
The valance electrons. The outer level of electrons every atom has. Every atom has a full valance shell at 8, so only the Nobel gasses are nonreactive naturally and other atoms either donate or accept the number of electrons needed to come to an octet of electrons.

How many valance electrons dose calcium have?
2
Which particles of the atom participate in the formation of chemical bonds?

Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.
What elements have 2 valance electrons?

Does calcium have three electrons in its valence shell yes or no?
No. It has Two electron in its valance shell.
What is the highest occupied energy level of Ba?
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.

With an ionic bond, valance electrons are transferred from one atom to another. Once transferred, the electrons orbit only around the atomic nucleus that has received them.
How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
