F - Fluorine
Explanation:
Fluorine is the atom that is most able to attract electrons to itself among the choices. The ability of an atom to attract electron to itself is called electronegativity.
- Electronegativity is a measure of the relative tendency with which atoms of an element attracts valence electrons in a chemical bond.
- Fluorine is the most electronegative element on the periodic table.
- According to Pauling's table on electronegativities of elements, it has a value of 4.0.
- This is the highest on the periodic table of elements.

The chemical characteristics or reactivity of a chemical element is highly (mostly) dependent on the: number of valence electrons in its outermost shell.
<h3>What is
chemical characteristics?</h3>
A chemical characteristic can be defined as the properties of a chemical element or compound that is mainly observable and measurable during a chemical reaction such as reactivity.
<h3>What is a valence electron?</h3>
A valence electron can be defined as the number of electrons that are present in the outermost shell of an atom of a chemical element.
In Chemistry, the number of valence electrons (valency) is a property that is typically used to determine the chemical characteristics or reactivity of all chemical elements.
In conclusion, the chemical characteristics or reactivity of a chemical element is highly (mostly) dependent on the number of valence electrons in its outermost shell.

Explanation:
If you look back at the formula ( SO2 ), you can see that there is one sulfur and two oxygens present. Therefore, the molar mass of sulfur dioxide is [1 × 32.1 + 2 × 16.0] = 64.1 g/mol.
Answer:
C. The theory that states that all molecules are constantly moving
Explanation:
The Kinetic Molecular Theory states that all molecules are constantly moving.
A and B are wrong. There are no such theories.
D is wrong. Modern atomic theory describes the energy levels of electrons.
