What is the mass number of As-3?
The mass number of an element is the sum of the number of protons and neutrons in its nucleus. Arsenic typically has a mass number of around 75, so As-3 would likely have a mass number of 72 since the isotope notation includes the mass number.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
What is the atomic number and the mass number of an element with 20 atomic number and 23 mass number?
The element with atomic number 20 is calcium. The mass number 23 indicates the total number of protons and neutrons in the nucleus of the atom. Since the mass number is 23 and the atomic number is 20, the number of neutrons in this calcium atom would be 3 (23 - 20).
What element has the mass number of 37?
The element with a mass number of 37 is chlorine (Cl).
Distinguish between the atomic number and mass number of an element?
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
What has a mass number of seven?
Lithium is an element with an atomic number of 3 and an atomic mass of 7.
What is the mass number of As-3?
The mass number of an element is the sum of the number of protons and neutrons in its nucleus. Arsenic typically has a mass number of around 75, so As-3 would likely have a mass number of 72 since the isotope notation includes the mass number.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
What is the atomic number and the mass number of an element with 20 atomic number and 23 mass number?
The element with atomic number 20 is calcium. The mass number 23 indicates the total number of protons and neutrons in the nucleus of the atom. Since the mass number is 23 and the atomic number is 20, the number of neutrons in this calcium atom would be 3 (23 - 20).
What is the mass number of the element vanadium?

What is the mass number for lithium?
Lithium is element #3. That, of course, is the atomic number - the number of protons. The atomic mass will of course depend on the specific isotope. The most common isotope is Lithium-7, that is, atomic mass = 7. Lithium-6 also occurs in nature as a stable isotope.
Which element has with mass number 27?
The element with mass number 27 is cobalt, which has 27 as its atomic mass.
