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".
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
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 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.
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.
What is the total number protons and neutrons in an atom called?
mass number = protons + nuetrons
The combined number of protons and neutrons?
Number protons + number neutrons is called the mass number or the atomic mass.
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
What is the mass number minus the atomic number called?
Nucleon Number (total number of protons and neutrons)
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.
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
What is the total count of the neutrons an protons in an atom?
The sum is called mass number.
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.
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.
Protons and neutrons together are known as?
no there are different elements, and you can check a periodic table for more information.
What is it called the total number of the positively charged and the uncharged particles?
number of protons + number of neutrons = mass number
