The number of neutrons in the nucleus of a silicon atom are?

A silicon atom typically has 14 neutrons in its nucleus. This number is calculated by subtracting the atomic number (14) from the mass number (28) of silicon.


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.


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


What is the mass number of silicon with 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.


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.


What does the atomic number of silicon tell you about number of protons neutrons and electrons?

The atomic number of silicon is 14. This means that a silicon atom has 14 protons in its nucleus, and a neutral silicon atom has 14 electrons. The number of neutrons depends on the particular isotope.


What is the total charge at the nucleus of silicon atom?

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


Number of atom for silicon?

The atomic number of silicon is 14. This means that a silicon atom contains 14 protons.


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 silicon mass number?

The mass number of silicon is 28. It is calculated by adding the number of protons and neutrons in the nucleus of a silicon atom. Silicon has 14 protons and 14 neutrons, giving it a mass number of 28.


If the atom has 14 protons and 12 neutrons what the atomic number?

The atomic number is the number of protons in an atom's nucleus, which in this case is 14. This is because the atomic number is determined by the number of protons in an atom, not the number of neutrons.


Consider the silicon 29 isotope How many protons and neutrons and electrons will it have?

All silicon atoms have 14 electrons and 14 protons. That is a rule that every silicon atom must follow. On the periodic table, the number next to the atom is the number of electrons/protons in an atom (silicon is the 14th element listed on the periodic table, hence the 14 electrons and 14 protons). The number "29" is the number of protons and neutrons together. This number can change with changing isotopes. So, if every silicon atom must have 14 protons, and 29 is the number of protons and neutrons together, so the number of neutrons must be 29 minus 14. Final: 14 protons 14 electrons 15 neutrons
