How is called the number of protons in an atom?
In a neutral atom, the number of protons is equal to the number of electrons. Therefore it is also equal to the atomic number of the particular atom.
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
What is the number of protons in an atom's nucleus?
The number of protons in a nucleus is called the proton number, or atomic number. It is what defines which element we have.
What is the particle that identifies a atom?
The number of protons in an atom's nucleus determines its chemical identity.
The sum of the numberof protons and nuetrons in the nucleus of an atom?
The sum of the number of the protons and neutrons in the nucleus of an atom is called as atomic mass.
Number of protons in a atom is called?
the atom's "atomic number"
The protons in the nucleus of an atom is called the?
the no. of protons or the no.of electrons inthe nucleus ofan atom is called the atomic number of that atom.
The number of protons in an atom of an element?
It is equal to the no. of electrons in the atom. It is called the atomic number.
How is called the number of protons in an atom?
In a neutral atom, the number of protons is equal to the number of electrons. Therefore it is also equal to the atomic number of the particular atom.
What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
The number of what in an atom is called the atomic number?
Protons
What is the total number protons and neutrons in an atom called?
mass number = protons + nuetrons
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
The number of protons in the nucleus of an atom is called the what?
Atomic number
What is it called when the number of protons in an atom change?
The only way to change the number of protons in an atom is with a nuclear reaction.
Number of protons in a an atom of an atom?
The number of protons in an atom is its atomic number.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
