The root mean square speed of a gas is calculated through the equation,
Vrms = sqrt (3RT/M)
where:
Vrms = root mean square velocity/speed
R = universal gas constant
T = temperature
M = molar mass of the gas
Fluorine gas is a diatomic particle, F2, with a molar mass equal to 37.997 g/mol. Substituting the known values to the equation,
Vrms = sqrt (3)(0.0821 L.atm/mol.K)(425 + 273.15)) / 37.997 g/mol))
Vrms = sqrt ((3)(0.0821 L atm)(101325 kg/ms²/1 atm))(698.15 K) (1 m³/1000L)/ (37.997 g)(1 kg/1000g))
Vrms = 25.63 m/s
ANSWER: 25.63 m/s

The atomic number tells you the number of electrons. That means there are 18 electrons in an argon atom.
Answer:
False, isotopes have different occurrence percentages, so the changes are different.
Explanation:
Hello,
In this case, since it is false that the isotopes of all the elements can be found with the same chance (occurrence) we can consider the following facts:
1. Carbon atom has two major occurring isotopes: C-12 (98.93%) and C-13 (1.07%).
2. Bromine atom has two major occurring isotopes: Br-79 (50.69%) and Br-81 (49.31%).
3. Calcium has four major occurring isotopes: Ca-40 (96.941%), Ca-42 (0.647%), Ca-43 (0.135%) and Ca-44 (2.086%).
Which show us that the chances of finding any isotope differ among elements.
Regards.
