MgCl2 is an ionic compound because chemical bonds in the molecule are formed by the transfer of electrons among Mg and Cl atoms.
<h3>What is chemical bond ?</h3>
A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds. Covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds," whereas dipole-dipole interactions, the London dispersion force, and hydrogen bonding are examples of "weak bonds" or "secondary bonds."
The positively charged protons in the nucleus and the negatively charged electrons in its orbit are attracted to one another by the basic electromagnetic force.

" check with someone to conform
Explanation:
Answer:
13: if thats one of the options
Explanation:
B/c for pH to be that high you have to have alot of OH ions and almost non H+. pH won't be 0 or 2 cuz that implies ALOT of H ions. pH wont be 7 cuz that implies we have 1*10^-7 H ions.
Answer:
He (helium, that is) has 2 protons in its nucleus.
Explanation:
The placement of numbers around an element's symbol can be confusing. Generally, an element symbol written in this format has the atimic mass in the upper left and the element number on the lower left. The upper right is the lement's charge, zero in the is case because there are two electrons and two protons, for a net charge of zero.
Some symbols will include additional information, such as electron configuration. Be aware of a publication's standard for the notation style used.
