How many neutrons does Silicon-30 have? 16 neutrons. Silicon-30 is an isotope of Silicon. It has a mass number of 30.

Does silicon have 15 neutrons?

For example, 92% of silicon in Earth’s crust is the isotope 28Si, which has 14 protons plus 14 neutrons. However, 5% of silicon atoms have 15 neutrons and another 3% have 16 neutrons, giving them atomic masses of 29 and 30 respectively.

How many protons neutrons and electrons is in SI 29?

Silicon-29 is composed of 14 protons, 15 neutrons, and 14 electrons.

How many protons neutrons and electrons does Silicon 28 have?

The atomic number is equal to the number of protons in the atom therefore silicon has 14 protons. In a neutral species the number of protons equals the number of electrons so silicon also has 14 electrons. The mass number is the number of protons plus neutrons therefore 28 – 14 protons equal 14 neutrons.

What has 15 electrons and 16 neutrons?

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 element has 18 protons and 22 neutrons?

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 element has 15 protons and 15 neutrons?

Explanation: If there are 15 protons, 15 nuclear particles of unit positive charge, then Z=15 . Now Z≡the atomic number , and you look at your copy of the Periodic Table, and you find that for Z=15 , the element phosphorus is specified.

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.

How many neutrons are there in a Si 34 atom?

Explanation: One atom of sulfur with an isotopic mass number of 34 has 18 neutrons. 34 (total) – 16 (protons) = 18 (neutrons).

How many protons neutrons and electrons are in silicon?

The atomic number is equal to the number of protons in the atom, therefore silicon has 14 protons. In a neutral species, the number of protons equals the number of electrons so silicon also has 14 electrons. The mass number is the number of protons plus neutrons, therefore 28 – 14 protons equal 14 neutrons.

What has 16 neutrons and 15 protons?

Explanation : if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.

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 .

Which element has 16 neutrons?

PHOSPHORUS – I am a member of the nitrogen family with 16 neutrons.
