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

Chemistry
1 answer:
Andreas93 [3]3 years ago
7 0

Answer:

Two electrons.

Explanation:

Calcium is the element of second group and forth period. The electronic configuration of Calcium is - 2, 8, 8, 2 or 1s^22s^22p^63s^23p^64s^2

There are 2 valence electrons of Calcium.

Iodine is the element of seventeenth group and fifth period. The electronic configuration of Iodine is - 2, 8, 18, 18, 7 or [Kr]4d^{10}5s^25p^5

There are 7 valence electrons of iodine.

Calcium iodide, CaI_2 is formed when 2 valence electrons of calcium are loosed and they are gained by 2 atoms of iodine.

can someone please explain me electronic arrangement of different elements please tomorrow is my paper i neEd help ASAP !!!!!!!
NNADVOKAT [17]

Answer:

This list of electron configurations of elements contains all the elements in increasing order of atomic number.

To save room, the configurations are in noble gas shorthand. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration.

hope this help

What volume of an hcl solution with a ph of 1.3 can be neutralized by one dose of milk of magnesia?
kvv77 [185]

274 mL H3 O+ and fully neutralized

It will take one teaspoon of Mg(OH)2 to completely neutralize 2.00×10^2mL  of H3O+.

<h3>What is the purpose of milk of magnesia?</h3>
  • For a brief period of time, this medicine is used to relieve sporadic constipation.
  • It is an osmotic laxative, which means that it works by drawing water into the intestines, which aids in causing bowel movement.

A chemical formula shows the kinds and numbers of _____ in the smallest representative unit of a substance.
Firdavs [7]

A chemical formula shows the kinds and numbers of <u>atoms</u> in the smallest representative unit of a substance.

<u>Explanation:</u>

In chemistry, a  formula unit is the empirical formula of "ionic or covalent network solid compound" that is used as an independent entity for "stoichiometric calculations". This formula is a representation of a molecule that uses chemical symbols.

The unit is the lowest whole number ratio of ions represented in an ionic compound. It gives the numbers of atoms representing the "smallest representative" unit of a substance. The number of atoms also tells us about the chemical and physical properties of the compound formed.
