How many protons neutrons and electrons are in a neutral atom of neon if its atomic number is 10 and its mass number is 22?
10 protons, 10 neutrons, 12 electrons
What is the number of subatomic particles for neon?
30 10 protons 10 neutrons 10 electrons
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.
How many protons neutrons and electrons would an atom of neon have?
- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number
How many protons neutrons electrons does nitrogen-20 have?
10 neutrons(uncharged) 10 neutrons(uncharged)
What is the mass of an atom that has 10 protons 13 neutrons 10 electrons?
The mass number of this atom is 23, the sum of the number of protons and neutrons.
Calculate the number of protons of the atom whose mass number is 19 and whose number of neutrons is 10?
Mass number 19 means a total of 19 protons and neutrons. If it has 10 neutrons, that leaves 9 protons, which is Fluorine.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
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.
An atom that contains 15 protons and 10 neutrons within its nucleus will have an atomic mass of?
The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
How many protons neutrons and electrons are in a neutral atom of neon if its atomic number is 10 and its mass number is 22?
10 protons, 10 neutrons, 12 electrons
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
How many neutrons does F-19 have?
The atomic number of Florine is 9 so it has 9 Protons in its nucleus. As the mass number of an atom is essentially the mass of the nucleus and as the mass of each Proton or Neutron is 1 this means that if there are 9 Protons there must be 10 Neutrons present to make up a mass number of 19.
What is the number of subatomic particles for neon?
30 10 protons 10 neutrons 10 electrons
How many protons and neutrons in the fluorine?
Fluorine has an atomic number of 9. Therefore it has 9 protons and electrons. It has an atomic mass of 19 amu. Therefore, the number of neutrons present can be calculated by subtracting the number of protons from its mass, i.e., 19-9=10. thus, fluorine has 9 protons and 10 electrons.
An atom with a mass number of 18 that contains 10 neutrons would have the atomic number of what?
8. Mass number is the number of neutrons plus the number of protons. The number of protons gives the atomic number.
What is the mass number of an atom with 6 protons and 10 neutrons?
mass number= no. of neutrons + no. of protons so the mass number will be 6+8 which is 14 the mass number = 14 :)
What element has a mass number of 10?
A mass number of 10 means the total of protons and neutrons is 10. It can be either:Boron-10 has five protons and five neutrons but also can have 6 neutrons.Beryllium-10 has four protons and six neutrons. It is very rare and decays to boron-10. Beryllium-9 is much more common with four protons and fiveneutrons.
