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?
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)
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.
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.
Standard atomic mass is based on what element?
Carbon 12 isotope weighs exactly 12 atomic mass units thank you the other person who said it was B is a douche

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.
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, the proton number decides, whether they are of the same element. In this case, they are isobars.

What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
Calculate the percent of water of FeSO47H20?
1. Find the molar mass (MM) of the substances.MM FeSO4 = 151.91g+MM 7H2O = 126.11gMM FeSO4 x 7H2O = 278.02g2. Find the percent water of hydrate.Divide the mass of water by the mass of the hydrate; multiply result by 100%.126.11g278.02g x 100%Percent water of FeSO4 * 7H2O is 45.36%.Finding Molar Mass# atoms Element A x atomic mass Element A = Mass A# atoms Element B x atomic mass Element B = Mass B... etc.Add up all the mass values for the substance and you have the molar mass of the substance.
What is the average atomic mass of unobtanium-221?
Perhaps it did not occur to you but unobtanium is an element which cannot be obtained!
