The number of protons in an atom is the atomic number. It tells you which element the atom is.
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.
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
The number of protons in a nucleus is called the proton number, or atomic number. It is what defines which element we have.
The sum of protons and neutrons in an atom is called mass number.
The number of protons in an atom is called the atomic number. It determines the element's identity and its place on the periodic table.
mass number = protons + nuetrons
the atom's "atomic number"
the no. of protons or the no.of electrons inthe nucleus ofan atom is called the atomic number of that 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.
Protons
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.
mass number = protons + nuetrons
Atomic number
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
The only way to change the number of protons in an atom is with a nuclear reaction.
The number of protons in an atom is its atomic number.
The number of electrons should equal the number of protons, otherwise you have an ion.
