Atomic number of Al is 13. It contains 13 protons.
The atomic number of aluminium is 13. So there are 13 protons in aluminium.
The nucleus of a silicon atom contains 14 protons.
Each atom has a unique combination of protons, neutrons, and electrons.
Each of whats atoms contain? Your question is non sense. Every type of atom has a different number of protons
One Uranium atom contains 92 protons as its atom number is 92. Therefore, 6 atoms contain 6*92=552 protons.

If an atom has 18 protons, it is neutral and will have the same number of electrons, which is also 18. In a neutral atom, the number of protons equals the number of electrons, balancing the positive and negative charges. Therefore, an atom with 18 protons will contain 18 electrons.
5. If it is more or less than 5 protons then it is not boron.
A neutral atom contains the same number of electrons as protons. Therefore, an atom with 18 protons will also have 18 electrons to maintain an overall neutral charge.
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
