Chemistry
1 answer:

Answer:

Magnesium and calcium belong to the second group i. e. alkaline earth metals. They are known as earth metals because they are extracted from the earth. They are very reactive elements. Their reactivity increases when we go from top to bottom because the outermost electrons goes farther from the nucleus i. e. atomic radius increases so less energy is needed for its removal.

An ionic bond would form between which pairs of elements? atomic number 4 and atomic number 18 atomic number 7 and atomic number
weeeeeb [17]

Answer:

atomic number 8 and atomic number 12

Explanation:

atomic number 8 and atomic number 12 , element with the atomic number 8 is oxygen, and the element with atomic number 12 is Magnesium

Magnesium has low ionization energy, hence higher tendency to loose its two outermost electrons to form positive ion.

Oxygen has high electron affinity, hence higher tendency to accept or gain electrons to form negative ion.

The electronegativity difference between the element with atomic number 8 and element with atomic number 12 is greater for the formation of ionic bond

Which electron are the valence electron of the atom
mart [117]

Answer:

In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
