14
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.
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.
There are 14 protons in 29Si. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying silicon-29) is unneeded.
The proton number is the atomic number.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
this elemnt has an atomic number that is double the atomic number of silicon?
The group number for silicon is 14.
The atomic Number of Silicon is 14.
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
A neutral silicon atom will have 14 electrons, one for each proton in its nucleus. A link follows and can be found below.
The element with double the atomic number of silicon is germanium, which has an atomic number of 32 compared to silicon's atomic number of 14.
Silicon is the 2nd member of carbon family its Atomic no is 14.
