14 neutrons
Silicon has 14 protons and 14 electrons, however Silicon has numerous known isotopes with mass numbers ranging from 22 to 44. These isotopes are caused by silicon having differing numbers of neutrons in its nucleus. (this is true for most elements). There is therefore no single answer to your question.
The stable isotopes of silicon are:
28Si (the most abundant isotope, at 92.23%) (Neutrons 14)
29Si (4.67%) (Neutrons 15)
30Si (3.1%) (Neutrons 16)
The Radioactive Isotopes are:
22Si (Neutrons 8)
23Si (Neutrons 9)
24Si (Neutrons 10)
25Si (Neutrons 11)
26Si (Neutrons 12)
27Si (Neutrons 13)
31Si (Neutrons 17)
32Si (Neutrons 18)
33Si (Neutrons 19)
34Si (Neutrons 20)
35Si (Neutrons 21)
36Si (Neutrons 22)
37Si (Neutrons 23)
38Si (Neutrons 24)
39Si (Neutrons 25)
40Si (Neutrons 26)
41Si (Neutrons 27)
42Si (Neutrons 28)
43Si (Neutrons 29)
44Si (Neutrons 30)
Silicon always has 14 protons and 14 electrons in each atom but the number of neutrons can vary from 8 to 30. This variation makes the 'isotopes' of Silicon. Silicon28 is the most abundant isotope (92.23% of all Silicon) and this has 14 neutrons.
In the most common isotope of silicon, there are 14 neutrons.
A stable silicon atom has 14, 15 or 16 neutrons.
There are 14 protons, 14 neutrons and 14 electrons in a silicon (SI)
It has 14 protons and, unless it is an isotope, 14 neutrons.
14, for the most stable isotope
Mass number is the sum of protons and neutrons in the nucleus of an atom. The atomic number of silicon is 14, so the number of protons in the nucleus of a silicon atom is 14. If the isotope of silicon has 14 neutrons, then the sum of protons and neutrons is 28.
Silicon has 14 protons and 14, 15 or 16 neutrons in the stable isotopes found in nature. These are located inside the nucleus.
Silicon has 14 protons and 14 electrons. The number of neutrons varies depending on the isotope of Silicon, but on average, Silicon has 14 neutrons.
There are 77 Neutrons in the nucleus of one atom of Xenon
Aluminium with atomic number 13 ie 13 protons has 14 neutrons within the nucleus. So its mass number is 27. Silicon too with atomic number 14 has 14 neutrons within. Why not? Even phosphorous with atomic number 15 has 14 neutrons. So it is an isotope that too radio active isotope. So it is very important to know about the number of protons to identify the element. But number of neutrons do differ leading to the formation of isotopes.
How many protrons and neutrons does silicon have in the nucleus?
silicon-28 as 14 protons and 14 neutrons in the nucleus and 14 electrons revolving around the nucleus
the nucleus of silicon contains neutrons and protons. neutrons are electrically neutral. The atomic no. of Si is 14, which means the Si nucleus contains 14 protons, so the charge at the nucleus of silicon atom is +14
14
Mass number is the sum of protons and neutrons in the nucleus of an atom. The atomic number of silicon is 14, so the number of protons in the nucleus of a silicon atom is 14. If the isotope of silicon has 14 neutrons, then the sum of protons and neutrons is 28.
Silicon has 14 neutrons.
Silicon has 14 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a silicon isotope = Mass number - 14
Silicon has 14 protons and 14, 15 or 16 neutrons in the stable isotopes found in nature. These are located inside the nucleus.
between 14 an 16
Silicon has 14 electrons and 14 neutrons
In the most common isotope of silicon, there are 14 neutrons.
A neutral atom of Silicon-27 contains 14 protons, just like any atom of Silicon (Si). Silicon has an atomic number of 14. The most abundant form of Si is Silicon-28, which has 14 neutrons. Silicon-27 has 13 neutrons.
