Neon has a mass number of 20(protons and neutrons) and a proton number of 10(electrons/protons)
The number of protons is equal to atomic number: neon 10 has protons.
The number of electrons that a nucleus has is equal to the elements' atomic number, found on the periodic table. In the instance of neon (Ne), its atomic number is 10; therefore, it has 10 protons.
An atom of neon consists of 10 protons, 10 neutrons and 10 electrons (atomic number = 10; atomic mass = 20)
The atomic number is the number of protons in an atom of an element. For example, Sodium's atomic number is 11. This tells us that an atom of sodium has 11 protons in its nucleus. The interesting thing here is that every atom of sodium contains 11 protons. If an atom doesn't have 11 protons, it can't be an atom of sodium. Adding or removing protons from the nucleus of an atom creates a different element. For example, removing one proton from an atom of sodium creates an atom of neon.
Neon atoms have 10 protons, and a neutral atom has 10 electrons. The number of neutrons can vary, but the most common natural isotope (90.5%) has 10 neutrons. Neon-21 (11 neutrons) is about 0.25% of natural neon, and neon-22 (12 neutrons) is about 9.25%
The number of protons is equal to atomic number: neon 10 has protons.
The atomic number is the number of protons in an atom. The number of protons in an atom is what gives the atom its elemental identity. The number of neutrons can change resulting in different isotopes of the same element. The number of electrons can change, resulting in different valence states of the same element. If the number of protons changes, then an atom of neon is no longer neon. So the atomic number of neon is always 10, because neon always has 10 protons.
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
The number of electrons that a nucleus has is equal to the elements' atomic number, found on the periodic table. In the instance of neon (Ne), its atomic number is 10; therefore, it has 10 protons.
Neutrons = 10. Protons = 10. And electrons = 10.
10 (neon)
The noble gas neon has ten protons and an equal number of electrons.
Neon atoms have 10 protons.
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
it shows how many protons are present in an atom
Neon has 10 protons and 10 electrons. Calcium has 20 protons and 20 electrons.
An atom of neon consists of 10 protons, 10 neutrons and 10 electrons (atomic number = 10; atomic mass = 20)
