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?
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 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.
Atomic number describes what?
Atomic number describes about number of protons.It is equals to number of protons.
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.

What is the atomic mass rounded of boron?
Boron - B - Group IIIThe atomic number is 5.The mass number is 11.
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 do element B Ge have in common?
Both element B (boron) and Ge (germanium) are metalloids, meaning they have properties of both metals and nonmetals. They also have similar atomic structures, with boron having atomic number 5 and germanium with atomic number 32.
What is all of the nonmetals for which the atomic number is a multiple of five?
The nonmetals with atomic numbers that are multiples of five are boron (atomic number 5), nitrogen (atomic number 7), phosphorus (atomic number 15), arsenic (atomic number 33), and iodine (atomic number 53).
What is the mass number of boron?
Atomic mass number of boron(B) - 11
What is the fifth element on the periodic table of elements?
The fifth element on the periodic table of elements is boron. It has an atomic number of 5 and is a metalloid with various industrial applications.
Phosphorus has an atomic mass of 31 and an atomic number of 15 the number of neutrons must be?
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
