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.

What element contains 14 protons and 15 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.
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.
What has 14 neutrons?
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 protons neutrons and electrons does silicon-30 have?
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
How many protons neuton and electrons does silicon have?
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.
What is the subatomic particle os a silicon?
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
What are the subatomic particles in silicon?
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
How many electrons does silicon-28 have?
Silicon atoms, atomic number 14, have 14 protons in the nucleus. The neutral atom then has 14 electrons. Silicon 28 the most common isotope of silicon has 14 neutrons in the nucleus giving a mass number of 28. The atomic mass of silicon 28 relative to carbon12=12. is 27.9769265325(19)
How many protons electrons and Neutrons does the element Silicon have?
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

How many protons neutrons and electrons does silicon-30 have?
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
A neutral atom contains 12 neutrons and 14 electrons. The mass number and the number of atom are respectively?
The mass number is 26. This is the isotope silicon-26 with the atomic number 14.
How many protons and neutrons are in silicon?
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).
How many protons and neutrons and electrons are there in a neutral atom of silicon-28?
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.
How many electrons does silicon -28 have?
Silicon atoms, atomic number 14, have 14 protons in the nucleus. The neutral atom then has 14 electrons. Silicon 28 the most common isotope of silicon has 14 neutrons in the nucleus giving a mass number of 28. The Atomic Mass of silicon 28 relative to carbon12=12. is 27.9769265325(19)
