Which ion below would have the smallest radius? Na+ Mg2+ 02- F

Chemistry
1 answer:
nadezda [96]2 years ago
5 0

Answer:

F, Fluorine

Explanation:

Na^+ and Mg^2+ have both lost enough electrons to bring their electron shells to that of Neon, Ne.  (1s^2, 2s^2, 2p^6)

O^2- gained 2 electrons to also conform to neon's electron configuration.

F still retains its 1s^2, 2s^2, 2p^5 configuration, which would result in a slightly smaller radius as the 2p^5 electrons can pack slightly closer to the nucleus before being repelled by the negative charge of their neighboring electrons.

Polymerization starts at the ________ end of the template.
balandron [24]

Answer:

B.  3'

Explanation:

Polymerization is the process of forming large molecules by joining together many small molecules. The small molecules are known as the monomers, and the macromolecules are called polymers.

There are two(2) types of polymerization.

a. addition polymerization

b. condensation polymerization

Polymerization is characterized by eliminating small molecules such as water, carbon(IV)oxide, methanol e.t.c.

In complex compounds, polymerization starts at the 3' end of the template.

Which type of bonding involves the complete transfer of a valence electron from a less electronegative atom to a more electroneg
Ivan

Answer:

Ionic or electrovalent bonds

Explanation:

Ionic or electrovalent bonds are interatomic or intramolecular bonds which are formed between two kinds of atoms having a large electronegativity difference usually 2.1.

Electronegativity is the property that combines the ability of an atom to gain or lose electrons. It is expressed as the tendency with which atoms of elements attracts valence electrons in a chemical bond.

In this bond type, a metal transfers its electrons to a more electronegative atom which is a non-metal.

Explain why is it better to use images on hazard labels, rather than words
enot [183]
In the case of an emergency where you might not have enough time to read several lines of writing, not to mention trying to find the hazard warnings when the whole bottle is probably covered in writing, it is much easier to locate and read universal hazard symbols.
