Mass number/Atomic Mass
Protons and Neutrons compose the nucleus of an atom. Protons and nutrons weight combine to give the mass of the atom. In most atoms, the amount of Neutrons is equivalent to the amount of Protons.
The building block of all matter are atoms. All matter is made out of atoms, atoms in turn are made out of protons, neutrons and electrons.
Depends on the atom. The atomic number will give you the number of protons. The atomic weight will give you approximately the number of protons and neutrons combined.
yes, all aluminum atoms have the same number of protons. The number of protons in an atom give it its identity. Isotopes are different atoms of the same element with the same number of protons, but a different number of neutrons.
In Chemistry, the building blocks of all matter are atoms. An atom cannot be chemically subdivided. Atoms are composed of protons, electrons, and neutrons. Protons and neutrons are found in the nucleus of the atom. Protons are positively (+) charged, while neutrons have no charge (are neutral). Electrons orbit around the nucleus on shells. The electrons are negatively charged. Protons and neutrons are responsible for the Atomic Mass while electrons will always be the same as the number of protons, which will give you the atom's atomic number.
An atom is the basic unit of matter consisting of a nucleus (protons and neutrons) surrounded by electrons. Two examples of atoms are hydrogen, which has one proton and one electron, and oxygen, which has eight protons, eight neutrons, and eight electrons.
atomic mass number - protons = number or neutrons
yes, all normal atoms do, but there are things called ions and isotopes that have fewer or more electrons and neutrons
An atom of iron has 26 protons. An atom of oxygen has 8 protons. The atoms are significantly different.
protons will tell the atomic number (8) the sum of protons and neutrons will give the mass number of the element
Protons make up the identity of the element and give it its unique properties. Protons have a positive charge. Neutrons give an atom additional mass, and the number of neutrons in an atom make it an isotope of an element. Neutrons have no charge.
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.
