What two particles make up the atomic mass?
Protons and Neutrons.
Which two subatomic particles make up the atomic weight of an atom of an element?
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
Iodine atomic number and atomic mass?
the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127
What is atomic mass A and neutron number N for given atom?
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
What 2 atomic particles make up the mass of an atom?
Protons and neutrons. Electrons have a too little mass.
What does an element's atomic mass tell about the atoms that make up that element?
Atomic Mass is the no. of protons+no. of nuetron
What does an element's atomic mass tell us about the atoms that make up that element?
atomic mass is the no. of protons+no. of nuetron
Do isotopes have the same atomic mass?
Nope, their chemical make up changes, changing the total atomic mass.
What two particles make up the atomic mass?
Protons and Neutrons.
Which two subatomic particles make up the atomic weight of an atom of an element?
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
What is the sum of protons and nuetons in the nucleus of an atom?
they make up the atomic mass of the element.
Iodine atomic number and atomic mass?
the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127
What is the atomic mass of atoms made of?
The Atomic Mass is made up of protons and neutrons (which is basically the nucleus.)
How do you find the atomic mass of C7H8?
You mean molecular mass or moler mass, not atomic mass! Add up the atomic masses of all the atoms in the molecule.
What is aluminum's atomic mass?
Aluminum's atomic mass is 26.9815386,but if rounded up,it is 27.
What is atomic mass A and neutron number N for given atom?
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
