Potassium ion (K+) ; 18 e- = [Ar]
Highest noble Gas is [Ar] at 18 e-
Neutral K is 19 e- with shorthand: [Ar] 4s1
eliminating an electron, eliminates 4s1 and makes it same configuration as Argon.
It is a star, since it glows and is very hot.
Answer:
Molecular mass
Explanation:
Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.
Thus,
Molecular mass = n × Empirical mass
Where, n is any positive number from 1, 2, 3...
Thus if the molecular mass is known, then we can find the value of n which results to molecular formula.
Answer:
Both contain a hydroxyl group on the second carbon.
Neither contain a hydroxyl group on an end chain carbon.
Explanation:
2,2-butanediol Formula: C4H10O2
