How many neutrons does an aluminum have?
13Aluminium / Atomic number
How many neutrons and electrons are in aluminum?
Answer and Explanation: Aluminum has 13 protons, 13 electrons, and 14 neutrons.
Is aluminum 12 or 14 protons?
A quick looks in the periodic table will show that aluminium has an atomic number equal to 13 . This means that any atom that is an isotope of aluminium will have 13 protons in its nucleus.
How do u find neutrons?
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
What element has 18 protons and 22 neutrons?
Argon So, the atomic number is also (18), and the element with atomic number (18) is Argon with the symbol (Ar). Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons. So, it is clear that this is not an isotope but a neutral atom of Argon.

What is a neutrons mass?
neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
What has 17 protons and 18 neutrons?
Answer and Explanation: Chlorine-35 has 17 protons and 18 neutrons.
What has 16 protons and 18 neutrons?
So, if there are 16 protons, the element must be sulfur. The mass number for this isotope is 34 – there are 16 protons and 18 neutrons.
How do you calculate number of neutrons?
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. Both of these numbers can be found on the periodic table.
Why is the mass of a neutron 1?
Relative Mass of Neutron Since protons are about 99.86% as massive as neutrons and electrons are about 0.054% as massive as neutrons. The relative mass of each particle of an atom is in kilograms. So, the relative mass of a neutron is 1.
What element has 22 neutrons?
argon Since, a neutral atom of argon also has 22 Neutrons.
Which element has 16 neutrons?
PHOSPHORUS 16. PHOSPHORUS – I am a member of the nitrogen family with 16 neutrons.

| Particle | Symbol | Mass (amu) |
|---|---|---|
| proton | p+ | 1 |
| electron | e− | 5.45 × 10−4 |
| neutron | n0 | 1 |

Which element has 15 neutrons?
Therefore the isotope with 14 protons and 15 neutrons is Silicon-29.
How do you find neutrons?
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
How do you calculate neutrons?
Finding the Number of Neutrons The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. Both of these numbers can be found on the periodic table. The atomic number is listed above the symbol of the element whereas the mass number is placed below.
What has 16 neutrons and 15 electrons?
Phosphorus The chemical symbol for Phosphorus. A 2 dimensional representation of a Phosphorus atom with 15 protons and 16 neutrons in the nucleus and 15 electrons orbiting the nucleus.
What is in a neutron?
A neutron is made of 3 quarks, one up quark, and 2 down quarks and many many "intermediate particles" called gluons which carry the interaction between the quarks. These gluons are exchanged very often, so the quarks feel each of other. Neutrons do not always decay.

What has 15 protons and 16 neutrons?
Phosphorus Phosphorus has 15 protons and 16 neutrons in its nucleus giving it an atomic number of 15 and a atomic mass of 31. Phosphorus is in Period 3 of the Periodic Table because it has 3 electron shells.
What element has 15 protons and 17 neutrons?
Phosphorus 32 Phosphorus 32 (P-32) is the phosphorus isotope whose nucleus consists of 15 protons and 17 neutrons. It disintegrates by emitting a β- (1.71 MeV) particle in 32S with a half-life of 14.263 days. It is an artificial radioactive substance obtained by neutron bombardment of stable phosphorus.
How is the number of neutrons?
The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
How do you figure out neutrons?
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. Both of these numbers can be found on the periodic table.
What element has 16 protons and 18 neutrons?
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur, S .
What has 16 protons and 15 neutrons?
Phosphorus Phosphorus – Key Stage Wiki.
How do you write neutrons?
The difference between the neutron number and the atomic number is known as the neutron excess: D = N − Z = A − 2Z. Neutron number is not written explicitly in nuclide symbol notation, but can be inferred as it is the difference between the two left-hand numbers (atomic number and mass). : Carbon-14 specifically.
What element has 17 protons and 18 neutrons?
chlorine atom Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei.
What has 18 protons and 20 neutrons?
You gots Z=18 , the atomic number, where Z is the number of nuclear protons. The number of protons defines the element….and thus we got calcium…. ….and with 20 neutrons we got the 38Ca isotope….the which is rather short-lived….
