29 SI (Neutrons 15)
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
An element with no. of protons=14 means its atomic number is 14, is an isotope of silicon.its mass number=14+16=30hence the element is 30Si,its abundance is 3.1%
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.
Sodium atoms always have 11 protons. Since the mass number is the sum of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from this number. Thus, sodium 25 has 14 neutrons.
Mass number = proton number + neutron number SO, Mass number(Aluminium) = 13+ 14 =27
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
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.
Silicon-27 has 14 protons (since it is silicon) and 13 neutrons, as the atomic number (proton number) minus the mass number (proton number + neutron number) gives the number of neutrons. In this case, 27 - 14 = 13 neutrons.
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
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
There are 14 protons and 16 neutrons in 30Si and the atom is a stable isotope of silicon.
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
The number of neutrons is different for each isotope. Number of neutrons = Atomic mass of an isotope - 104
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
For each isotope of Md the number of neutrons is different.Number of neutrons = Mass number of a Md isotope -101
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
The atoms of all three isotopes have the same number of protons (14) and electrons, but differ in the number of neutrons: silicon-28 has 14 neutrons, silicon-29 has 15 neutrons, and silicon-30 has 16 neutrons. This variation in neutron number gives each isotope a different atomic mass.
