Frequent question: What is the name of the compound KI Why is it electrically neutral?

Potassium iodide is an ionic compound with the formula KI. It’s electrically neutral because it has equal amounts of positive and negative charge….

What is the compound KI called?

KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury.

Why is a compound electrically neutral?

In every ionic compound, the total number of positive charges of the cations equals the total number of negative charges of the anions. Thus, ionic compounds are electrically neutral overall, even though they contain positive and negative ions.

What is the compound for KL?

Transfer of electrons

During the reaction with potassium, the iodide atom gains an electron, leaving its outer energy level with eight electrons. This atom is no longer neutral because it gained an extra negative particle. It now has a charge of 1− and is called an iodide ion, written as I.

Is KI ionic or covalent?

Potassium iodide (KI) forms an ionic bond. Potassium and iodine have very different electronegativities. The two atoms would form an ionic bond since ionic bonds form between atoms with a large difference in electronegativity (difference>1.7 using the Pauling scale will result in an ionic bond).

What is electrically neutral?

The amount of charge on a single proton is equal to the amount of charge possessed by a single electron. A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.

How do you know if a compound is electrically neutral?

If an atom has the same number of protons and electrons, it is electronically neutral. However, if the total number of electrons does not equal the number of protons, the atom has a net electrical charge.

Is molecule electrically neutral?

A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.

Is KL a covalent compound?

Potassium iodide is an ionic compound.

What is KL element chemistry?

Potassium Iodide is a metal halide composed of potassium and iodide with thyroid protecting and expectorant properties.

Is KL an element?

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19.
