How many protons electrons and Neutrons does the element Silicon have?

Answer 1

Atomic number 14

it has 14 protons

it has 14 electrons, provided it is a silicon atom and not an ion with -4 charge

neutrons here are a variable. i dont know the percentages of each ion, but the Atomic Mass is 28.08, that rounds to 28, subtract 14 and silicon most commonly has 14 neutrons

Answer 2

See the Web Links for the stable isotopes of Si (subtract 14 from the number after "silicon" -- so for example silicon-30 has 16 neutrons).

A neutral Si atom has 14 electrons.

See the Related Questions to the left for how to determine the number of protons, neutrons and electrons in ANY atom!

Answer 3

Silicon's atomic number is 14.

Therefore it has 14 protons and 14 electrons.

The number of neutrons can vary by isotope.

Most silicon is silicon-28 with 14 neutrons.

There are stable isotopes with 15 or 16 neutrons.

The unstable (radioactive) isotope is silicon-32 with 18 neutrons (half-life 170 years).

Answer 4

Silicon has 14 protons and 14 electrons because it has the atomic number of 14.

The number of neutrons is less straightforward. Silicon (Si) has 24 known isotopes, with atomic mass numbers ranging from 22 (containing 8 neutrons) to 45 (containing 31 neutrons). However, by far the most common (92.23% of all Silicon) has an atomic mass of 28 (containing 14 neutrons). The next most common are 29 Si and 30 Si (containing 15 and 16 neutrons respectively). The other isotopes of Silicon are not stable and undergo radioactive decay.

Answer 5

Fourteen is your answer, because the Silicon's atomic number is fourteen making the Protons, Neutrons, and Electrons all the same number.

Answer 6

Silicon has 14 protons and 14 electrons.

Si-28 isotope has 14 neutrons.

Answer 7

Silicon's atomic number is 14. Thus it has 14 protons and 14 electrons. 28Si is its most common isotope, and it has 28 - 14 = 14 neutrons.

Answer 8

protons-14

neutrons-14

Answer 9

14 each in Si-28 isotope

Answer 10
