What is mass number equal to?
The mass number of an atom is defined as the total number of protons and neutron (collectively called "nucleons") in the atomic nucleus. For example, a helium atom with 2 protons and 2 neutrons would have a mass number of 4.
Why mass number denoted by A?
Mass number is the total number of protons and neutrons. because the nucleus consists of protons and neutrons only, the sum of protons and neutrons is the total number of ALL the nucleons. note the term "ALL" here.. this is the reason why mass number is denoted as "A".
A common isotope of carbon has a mass number of 13 The total number of protons and neutrons in the nucleus is?
13. The mass number is always the total number of protons and neutrons.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
Calculate the number of protons of the atom whose mass number is 19 and whose number of neutrons is 10?
Mass number 19 means a total of 19 protons and neutrons. If it has 10 neutrons, that leaves 9 protons, which is Fluorine.
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
How many protons are in an atom with atomic mass of 6 and mass number of 13?
The atomic number is equal to the number of protons in the nucleus. The mass number is equal to the total number of nucleons (both protons and neutrons). Therefore, there are 13 protons and neutrons, 6 of which are protons, leaving the remaining 7 to be neutrons. In short, 6 protons, 7 neutrons. You're referring to carbon-13, an uncommon isotope of carbon. Sharondenadel The atomic number is equal to the number of protons in the nucleus.

Total of proton and neutron in a molecule?
The atomic mass of a molecule is equal to the number of protons plus the number of neutrons.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What is the total number of protons and neutrons in sulfur?
Sulfur has 16 electrons, protons and neutrons.
What is mass number equal to?
The mass number of an atom is defined as the total number of protons and neutron (collectively called "nucleons") in the atomic nucleus. For example, a helium atom with 2 protons and 2 neutrons would have a mass number of 4.
Total number of particles in the nucleus is called what?
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.
The atomic mass of an atom is determined by the combined masses of its what?
The total number of protons plus the total number of neutrons
