A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is 84 in Krypton-84?

The 84 in Krypton, which is actually closer to 83.8), is the ATOMIC MASS. This is a number that allows one to track the number of atoms of krypton in a given amount of krypton or a substance containing it. The 83.8 means that in 83.8 GRAMS of pure Krypton, there is exactly one MOLE of Krypton. One mole is defined as being EXACTLY 2.2214179X10^23 atoms (Avogadro's number) of Krypton. That means, if we have something like 20 grams of Krypton, we can 'count' the molecules in this chunk of Krypton like this: (20grams Kr)(1Mol Kr / 83.8 grams) = 0.2386634845 moles of Krypton. From here, we multiply the number of moles by Avogadro's number, and we get: (0.2386634845 moles Kr)(2.2214179X10^23 atoms / mol) = 5.301713365X10^22 atoms of Kr in 20 grams of Kr.

How many protons and neutrons does Krypton have?

There are 46 protons 34 neutrons and 12 electronsThere are 36 protons and 48 neutrons in the most abundant isotope of krypton, krypton-84. To find the number of protons, just find the atomic number. This is the same as the number of protons. To find the number of neutrons, take the mass number and subtract the atomic number. For example, carbon-12 has an atomic number of 6 and a mass number of 12. Carbon-12 has 6 protons and 6 neutrons. There are isotopes that have different numbers of neutrons.
