If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
What is the average atomic mass of an element with isotopes a b and c?
(mass of A) x (%of A) + (mass of B) x (% of B) + (mass of C) x (% of C)
What has an atomic mass of 10.81 and starts with a b?
The element with an atomic mass of 10.81 and starting with "B" is Boron (B). It is a metalloid with symbol B and atomic number 5. Boron is commonly used in various industrial applications and as a dopant in semiconductor materials.
What is the atomic mass of the element boron?
The atomic number of Boron (B) is 5.The atomic weight of B is 10.811 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
Each element has its own characteristic atom in which a. the atomic weight is constant b. the atomic number is constant c. the mass number is constant?
b. the atomic number is constant. The mass number is not constant because there are isotopes of an element that have the same number of protons but different number of neutrons. Likewise, there are isotopes of the same element with different atomic weights.

If Atom A has mass number 239 and atomic number 93 and Atom B has a mass number 239 and atomic number 94 are atoms A and B of the same element and why?
No, atoms A and B are not the same element because they have different atomic numbers. The atomic number, which determines the element, is based on the number of protons in the nucleus. In this case, atom A has 93 protons while atom B has 94 protons, indicating they belong to different elements.
What is the atomic weight of bromine?
The atomic mass of Boron (B) is 11 but to be more accurate, the atomic mass is 10.81.
The average atomic mass of boron is 10.81 amu. Based on the atomic mass of B-10 and the relative abundances of the boron isotopes what is the atomic mass of B-11?
The atomic mass of boron-11 (B-11) can be calculated by setting up an equation based on the given average atomic mass of boron and the known atomic mass and abundance of boron-10 (B-10). Since the average atomic mass is a weighted average of the isotopes, the equation would be: (mass of B-10 * % abundance of B-10) + (mass of B-11 * % abundance of B-11) = average atomic mass of boron. Solving this equation will give you the atomic mass of B-11.
What is the relative atomic mass of an element whose isotopic composition is 90 percent b of 20X and 10 percent of 22 X?
