The mass number tells you the number of Protons and Neutrons in an atomic nucleus.
Atomic mass is the number of protons present in the nucleus or number of electrons revolving around the nucleus in an atom .It is denoted by Z. Mass number is the sum of number of protons and neutrons present in a nucleus in an atom .It is denoted by A.
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
Atomic number is the number of protons in the nucleus of an atom.Mass number is the number of protons plus neutrons in the nucleus of an atom of a specific isotope.Atomic mass is the total mass of a an atom of a particular isotope, not just the mass of the nucleus. Atomic mass is usually measured in atomic mass units (amu), and is the total mass of protons, neutrons, and electrons in an individual atom of the isotope.
The atomic mass number or nucleon number. The atomic mass number is written in superscript on the left of the elements symbol.
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
Atomic number tells how many protons are inside an atom's nucleus and therefore also how many electrons the atom has. An atom's mass number is the number of protons AND neutrons in the atom's nucleus and this will vary for each isotope of an element.
This tells us that an atom of krypton has 36 protons in its nucleus. All you really need to find is something called the mass number.
The mass number tells you the number of Protons and Neutrons in an atomic nucleus.
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
It tells you the average amount of protons and neutrons within the nucleus of an atom. In other words, atomic mass - atomic number (protons)= the number of neutrons within the nucleus.
The mass number is the sum of protons and neutrons in the nucleus of an atom.
Atomic mass is the number of protons present in the nucleus or number of electrons revolving around the nucleus in an atom .It is denoted by Z. Mass number is the sum of number of protons and neutrons present in a nucleus in an atom .It is denoted by A.
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
An atom with an atomic number of 9 has 9 protons; that's what the atomic number is, it tells you the number of protons in the nucleus.
The mass number is sum of neutrons and protons in the atomic nucleus.
The mass number is the number of protons and neutrons in the nucleus of an atom.
