The number of protons in a nucleus is called the atomic number, usually identified as the symbol Z. It defines the element in the Periodic Table. In a neutral atom, ie not ionised, there is an equal number of electrons
What else can I help you with?
When is an atom neutral When mass number equals number of protons equals number of electrons or when atomic number equals number of protons equals number of electrons?
An atom is neutral when the number of protons in the nucleus equals the number of electrons surrounding the nucleus. This means that the atom has no overall charge, as the positive charge of the protons is balanced by the negative charge of the electrons. The mass number, which is the sum of protons and neutrons, does not necessarily impact the neutrality of the atom.
The number of protons equals the atomic number?
Yes.
What number of particles in an atom usually equals the number of protons?
Unless it is an ion, the number of electrons will equal the number of protons.
What equals to the number of protons plus the number of electrons?
2 * Z
Is it true that the number of protons always equals the number of neutrons in all isotopes?
No. the statement is false.Number of positively charged protons always equals number of negatively charged electrons in a neutral atom

The number of protons equals the atomic number?
Yes.
What is the number of protons in a neutral atom equal to?
The number of protons equals the number of electrons in an uncharged atom.
The atomic number equals the?
It is found by m.g mosly. It is equals or protons that atom has.
What number of particles in an atom usually equals the number of protons?
Unless it is an ion, the number of electrons will equal the number of protons.
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.
Does valence electrons equals number of protons?
YES!!!!
What equals to the number of protons plus the number of electrons?
2 * Z
WHAT Equals the sum of the number of neutrons and protons in an isotope?
The atomic mass equals neutrons and protons. This is true in non isotopes as well.
What is the symbol that equals 79 protons?
The number of protons of an atom is equal to its atomic number, and element number 79 is gold (Au).
What particle defines an element?
The number of protons in an atom's nucleus determines the identity of element. The number of protons equals the atomic number.
Is it true that the number of protons always equals the number of neutrons in all isotopes?
No. the statement is false.Number of positively charged protons always equals number of negatively charged electrons in a neutral atom
