Is the number 18 abundant?
An Abundant Number is one that the factors (other than itself) add up to more than the number. 18 factors into [2 3 3] so the factor list is {1 2 3 6 9 18} and the sum of the rest is 21. Since 21 is greater than 18, it is an abundant number.Yes 18 is an abundant number because if you add all of it's factors (1,2,3,6,9,) together the sum is 21.Definition of Abundant- a number that is less the sum of it's factors or integers
What is the rational number between 1 10th and 1 11th?
There is no "the" rational" number since there is an infinity of them. Start with the number halfway between the two: (1/10+1/11)/2 = 21/220. Then try halfway between 1/10 and 21/220, and then halfway between 1/10 and that on. And so on.

An atom that has 11 neutrons and an atomic number of 10 has a mass number of what?
The mass number of this atom is (10 + 11 =) 21.Remember:Mass number is the sum of (the number of) neutrons (= 11) and protons.Atomic number is equal to the number of protons (= 10)This atom is the least abundant isotope of neon, 2110Ne (< 0.3%)
