The Atomic and mass number for calcium?
Calcium is a metal element. Atomic mass of it is 40.
What is the atomic mass 20 gas?
The atomic mass of an element is the average mass of an atom of that element. For a gas with an atomic mass of 20, it could be calcium (Ca). Calcium has an atomic number of 20 and an atomic mass of approximately 40.08 grams per mole.
What element has 18 protons 20 nuetrons and 18 electrons What is its atomic number?
The element with 18 protons is argon (Ar), with atomic number 18. Its mass number is calculated by adding the protons and neutrons, so 18 protons + 20 neutrons = mass number 38 for this particular isotope of argon.
What is neon's mass number?
The mass number of an element will depend on which isotope of that element is being considered. The element neon has three stable isotopes, and the mass numbers for them are 20, 21 and 22. This means that there will be 20Ne, 21Ne and 22Ne. Remember that all atoms of neon have 10 protons, regardless of which isotope. A link to the Wikipedia article on neon is supplied.

What is the atomic mass 20 gas?
The atomic mass of an element is the average mass of an atom of that element. For a gas with an atomic mass of 20, it could be calcium (Ca). Calcium has an atomic number of 20 and an atomic mass of approximately 40.08 grams per mole.
What is the identity of the element that has an atomic mass of 40.078 amu?
The element with an atomic mass of 40.078 amu is calcium. Calcium has an atomic number of 20.
Calcium atomic nummber is 20 what period is caluim?
We can find calcium as a non metal element. Atomic number of it is 20.
How is the atomic mass calculated for neon?
Neon is a non meta element. Atomic mass of it is 20. Atomic number of it is 10.
Calcium has an atomic mass of an atomic number of 20 so the number of neutrons must be?
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass. For calcium with an atomic number of 20, if the atomic mass is 40, then the number of neutrons would be 40 - 20 = 20 neutrons.
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.
