Answer: radon (atomic mass 222 amu
Explanation:
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:
atomic mass of krypton= 83.8 amu
atomic mass of argon= 39.95 amu
atomic mass of xenon = 131.3 amu
atomic mass of radon= 222 amu
Thus as atomic mass of radon is highest, its rate of diffusion is slowest.

A chemical formula shows the kinds and numbers of <u>atoms</u> in the smallest representative unit of a substance.
<u>Explanation:</u>
In chemistry, a formula unit is the empirical formula of "ionic or covalent network solid compound" that is used as an independent entity for "stoichiometric calculations". This formula is a representation of a molecule that uses chemical symbols.
The unit is the lowest whole number ratio of ions represented in an ionic compound. It gives the numbers of atoms representing the "smallest representative" unit of a substance. The number of atoms also tells us about the chemical and physical properties of the compound formed.
I think the charge is +2

Answer:
Yes A redox reaction can be a combination reaction.
Two elements are mixed in a combination reaction to produce a single product.
Explanation:
Example: water formula
2H2 + O2 → 2H2O
Oxygen is reduced in this reaction when electrons are transferred from hydrogen to oxygen and hydrogen is also oxidized since oxygen from hydrogen accepts electrons. Oxygen is the oxidizing agent and hydrogen is the reducing agent.
2H2 + O2 → 2H2O
