14 protons and 14 neutrons
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.
The mass number of an atom is the sum of its protons and neutrons. Silicon has 14 protons making its atomic number 14. With 14 neutrons added to 14 protons, the mass number of silicon with 14 neutrons would be 28.
Aluminum has 13 protons and 13 or 14 neutrons. Silicon has 14 protons, and 14 to 18 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.
The 14 protons means it has the atomic number 14, and from the periodic table you can see that it is silicon, Si. The 15 neutrons added to the 14 protons means it has a mass number of 29, and is an isotope of silicon called silicon-29.
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).
The mass number of an isotope is the sum of its protons and neutrons. Since silicon has 14 protons, the isotope with 15 neutrons would have a mass number of 14 (protons) + 15 (neutrons) = 29.
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'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).
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
A silicon (Si) atom has 14 protons and typically 14 neutrons. Protons are located in the nucleus at the center of the atom, while neutrons are also found in the nucleus alongside the protons. The number of neutrons can vary slightly due to the presence of isotopes, but the most common isotope of silicon has 14 neutrons.
The mass number of an isotope is the sum of its protons and neutrons. Silicon has an atomic number of 14, meaning it has 14 protons. If the isotope has 15 neutrons, the mass number would be 14 protons + 15 neutrons, which equals 29. Therefore, the mass number of the silicon isotope is 29.
