The atomic number of the element Si is 14.
The correct symbol for the element silicon is Si and the atomic number is 14.
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
silicon is the only element with an atomic number of 14. (Si is the symbol on a periodic table)
An atomic number represents the number of protons in the nucleus of an atom. It determines an element's identity and is unique to each element on the periodic table.
Silicon (Si) is a chemical element with an atomic number of 14. It has 14 protons in its nucleus, which defines its identity as silicon.
The correct symbol for the element silicon is Si and the atomic number is 14.
Si atomic number is 14. Atomic mass is 28.
A curie is a non-SI unit of radioactivity. It is not a chemical element and so does not have an atomic number.

The atomic number for aluminium is 13.
To draw a model of the atom with atomic number 16 and symbol Si, you would have a nucleus at the center with 16 protons and 16 neutrons. Around the nucleus, you would have 16 electrons orbiting in various energy levels, following the rules of electron configuration. The atomic weight of 28.0855 indicates the average weight of the isotopes of silicon.
