What elements would likely form an ionic bond? a. C & O
b. Mg & Cl
c. Mg & Ca
d. Cl & Ar
When electrons are from one atom to another, we say the bond is ionic.
a. transferred
b. shared
How many electrons does 47Ag+1 have?
107
47
48
46

b. Mg & Cl

a. transferred

46

Explanation:

Ionic bonds form between metals and non-metals when electrons are transferred from one specie to another.

The electrostatic attraction from the resulting ions forms the ionic bonds. A metal is electropositive and will readily donate electronsA non-metal is electronegative and will accept electrons. This creates two oppositely charge ions that attracts by means of ionic bonding.

Since Mg and Cl are the only metal - non-metal pair, and ionic bond will form between them.

2.

  In the specie;

          ₄₇Ag¹⁺

47 is the atomic number of the element Ag.

The atomic number is the number of protons in an atom. For a specie in neutral state, the number of protons and electrons are the same.

When an atom loses electron, it becomes positively charged. Here Ag has lost one electron and then, the number of electrons becomes 46. The number of protons is still 47

A. volume stays constant. just took took the quiz

Fine out your self ponk
