The Atomic and mass number for calcium?
Calcium is a metal element. Atomic mass of it is 40.
What is the mass number of Fluorine-20?
Fluorine is a non metal element. Atomic mass of it is 19.
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 has a atomic number 20?
Calcium is a meta element. Atomic number of it is 20.
What is the mass atomic number of potassium?
Name: PotassiumSymbol: KAtomic Number: 19Atomic Mass: 39.0983 amuThe atomic number is 19 and the mass number of its most abundant isotope K-39 is 39 (19 protons + 20 neutrons) while the mass of that isotope is 38.96371 a.m.u.The relative atomic mass of the element potassium, K, is 39.10 g/mole.
The Atomic and mass number for calcium?
Calcium is a metal element. Atomic mass of it is 40.
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.
What are the atomic numbers and atomic mass of neon?
Neon is a non meta element. Atomic mass of it is 20 Atomic number of it is1 180.
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.
What is the mass number of Fluorine-20?
Fluorine is a non metal element. Atomic mass of it is 19.
What is the atomic mass of the element Ne?
Neon is a non meta element. Atomic mass of it is 20.
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 is the mass number of an atom with 19 protons and 20 neutrons?
The element is potassium. Atomic mass is 38.
What is the chemical symbol of the element who is the mass number is 80?
A-N=Z Mass number - Number of neutrons= Atomic number mass number = 80, number of neutrons = 41; 80-41=39 Atomic number for the element with mass number 80 and 41 neutrons; is 39.
If an atom of an element has a mass number of 31 and 16 neutrons in its nucleus what is the atomic number of the element?
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
How do you find out the atomic mass of an element?
On the periodic table it is the number on the bottom of the element.If you know the amount of neutrons you can add it to the number of protons to find the atomic mass NUMBER, which is a good approximate of the atomic mass.Potassium (isotope 39), 19K(39), has 19 protons and 20 neutrons19 + 20 = 39 atomic mass NUMBER, its atomic mass is 39.10 a.m.u.
