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.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
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.
Which element is a transition element with a mass of 52?
The element with a mass number of 52 is Chromium (Cr). It's atomic number is 24.

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 for lithuim?
Lithium is a metal element. Atomic mass of it is 7.
What are the atomic and atomic mass numbers of nitrogen?
Nitrogen has a gram atomic mass of 14.0067, an atomic number of 7, and the chemical symbol N.
What is the mass number in nitrogen?
Nitrogen is a non metal element. Atomic mass of it is 64.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
How do you determine neutrons?
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
What is the atomic mass number A for N with 7n?
The atomic mass number A is the total number of protons and neutrons in an atom's nucleus. For nitrogen (N), the atomic number (number of protons) is 7. If it has 7 neutrons (designated as "7n"), then the atomic mass number A would be 14 (7 protons + 7 neutrons).
What is the atomic number of nitrogen -14?
The atomic number of nitrogen is 7. The atomic number represents the number of protons in the nucleus of an atom. The isotope "nitrogen-14" refers to an atom of nitrogen that has 7 protons and 7 neutrons in its nucleus.
If An element X has two isotopes. X and ndash15 has 7 protons and 8 neutrons. how the atomic number and mass number of the second isotope which has 10 neutrons in its nucleus.?
The atomic number of element X is determined by the number of protons, which is 7. For the second isotope, which has 10 neutrons, the mass number is the sum of protons and neutrons, calculated as 7 protons + 10 neutrons = 17. Therefore, the second isotope has an atomic number of 7 and a mass number of 17.
What is the mass number of the element vanadium?
Vanadium is a metal element. Mass number of it is 51.
