If you have 20 neutrons you are going to have somewhere in the vicinity of 20 protons. Potassium has 19 protons, so it must be potassium. Note that although protons and neutrons do not have to match (and don't far more often than not), there is no chance of the element being either Na (11 protons) or Rb (37 protons). After you get past the first couple of elements, it is really rare to find an isotope with a neutron to proton ratio much below 1:1 or much past 1.5:1, and the 1.5:1 ratio you see in really big nuclei.

What element which has the most abundant isotope which has 20 neutrons?
Potassium I reckon
What is an element with 20 neutrons?
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.
An element has 22 protons 20 electrons and 26 neutrons What isotope is it?
titanium
What element has 20 protons 22 neutrons and a plus 2 charge?
if you mean 2 valence electrons then it should be calcium because it is an alkaline earth metal and when you calculate the number of neutrons using the number of protons, 20 the atomic number, and the atomic mass, 40.078..rounded to 40, you get 20 neutrons.
What element has 20 protons and is found in teeth and bones?
Calcium
What is the chemical elements represented by the following symbol - K?
Potassium and it has 19 electrons and protons and 20 neutrons. Potassium and it has 19 electrons and protons and 20 neutrons. Potassium and it has 19 electrons and protons and 20 neutrons.
What is an isotope of the element with 20 protons and 20 neutrons?
Yes, the isotope potassium-39 has 20 neutrons.
What alkaline Earth Metal has 20 neutrons?
The only alkaline earth metal that has a stable isotope with 20 neutrons is calcium.
What is the element that has 20 neutrons?
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
What element 20 protrons 20 neutrons and 18 electrons?
Ca2+
An atom has an atomic number of 18 and 20 neutrons. what is the element?
Argon-20
What element has 20 neutrons and is foud in teeth and bones?
This element is calcium.
How many protons electrons and neutrons in the element kalsium?
1) it's spelt Calcium and 2) 20 protons, 20 electrons, 20 neutrons
An atom of an element contains 20 protons 20 neutrons and 20 electons This element is?
Calcium: The identity of an element is determined by how many protons each atom of the element has, and calcium is the name of the element with 20 protons per atom.
Calcium has an atomic mass of an atomic number of 20 so the number of neutrons must be?
The number of neutrons is different for each isotope of an element: Number of neutrons of an isotope = atomic mass of the isotope - atomic number of the element Calcium has also 20 protons and 20 electrons.
What element which has the most abundant isotope which has 20 neutrons?
Potassium I reckon
I have 20 neutrons and I am found in your teeth and bones?
Calcium is the answer. Atomic weight 40 - with 20 protons means 20 neutrons. Calcium is a key element in teeth and bones.
