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.
14 neutrons
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.
It varies depending on the isotope. The most common isotope (over 90%) has 14 neutrons.
C-13 has an atomic number of 6 and an atomic mass of 13, therefore it has 13-6 neutrons = 7. C-14 therefore has 8 neutrons. N-14 has an atomic mass of 14 and an atomic number of 7, so its number of neutrons is 7. 8>7, so Carbon 14 has the largest number of neutrons.
Carbon-12 has 6 protons and 6 neutrons. Isotopes of an element have different numbers of neutrons. So: carbon-14 has 8 neutrons and 6 protons.
Silicon has 14 neutrons.
14 protons and 14 neutrons
There are 14 neutrons in Silicon-28
14 neutrons
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.
6 neutrons in C-12 and 8 neutrons in C-14.
Aluminum has 13 protons and 13 or 14 neutrons. Silicon has 14 protons, and 14 to 18 neutrons.
Silicon has 14 electrons and 14 neutrons
7 neutrons in Nitrogen 14
It varies depending on the isotope. The most common isotope (over 90%) has 14 neutrons.
Si, other wise known as Silicon has 14 neutrons!
Silicon (Si) has 14 electrons, 14 protons, and usually 14 neutrons.
