The number of electrons can be determined by:
Neutron
Atomic number.
Protons balance Electrons
Electrons, Protons and Neutrons.
Number of protons × relative charge of a proton.
Number of electrons = A – N.
Atoms that have the same atomic number but different mass numbers.
The Nucleus.
The main subatomic particles are:
Neutron
Atomic number.
Protons balance Electrons
Electrons, Protons and Neutrons.
Number of protons × relative charge of a proton.
Number of electrons = A – N.
Atoms that have the same atomic number but different mass numbers.
The Nucleus.
The atom is electrically neutral since:
Neutron
Atomic number.
Protons balance Electrons
Electrons, Protons and Neutrons.
Number of protons × relative charge of a proton.
Number of electrons = A – N.
Atoms that have the same atomic number but different mass numbers.
The Nucleus.
The charge of the nucleus is equal to:
Neutron
Atomic number.
Protons balance Electrons
Electrons, Protons and Neutrons.
Number of protons × relative charge of a proton.
Number of electrons = A – N.
Atoms that have the same atomic number but different mass numbers.
The Nucleus.
The neutral particles are called:
Neutron
Atomic number.
Protons balance Electrons
Electrons, Protons and Neutrons.
Number of protons × relative charge of a proton.
Number of electrons = A – N.
Atoms that have the same atomic number but different mass numbers.
The Nucleus.
The mass of the atom is concentrated in:
Neutron
Atomic number.
Protons balance Electrons
Electrons, Protons and Neutrons.
Number of protons × relative charge of a proton.
Number of electrons = A – N.
Atoms that have the same atomic number but different mass numbers.
The Nucleus.
For X (Z,A), Z is the:
