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.
14
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
If a proton were added to an atom of aluminum, the atom would become a silicon ion with a single positive charge.
they differ only in the number of neutrons.
The silicon-29 isotope is used extensively in Nuclear Magnetic Resonance or NMR spectroscopy. It has 14 electrons, 14 protons and 15 neutrons.
Silicon has 14 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.
14
All silicon atoms have 14 protons
Regardless of the isotope, every silicon atom has 14 electrons.
The chemical symbol for the element Silicon is Si. If you wanted to distinguish Silicon 29 from other Silicon isotopes you would write 29Si.

The element copper (Cu).
The silicon-29 isotope is used extensively in Nuclear Magnetic Resonance or NMR spectroscopy. It has 14 electrons, 14 protons and 15 neutrons.
The atomic mass of 29Si is 28.976494700.
