An element X has atomic mass 27 and atomic number 13
i) Draw the atomic structure of an atom X, write the name and symbol.
ii)Write the number of protons ,electrons and neutrons in the nucleus of t atom X.​

Answer 1

X = Aluminum .

• Atomic number –Z = 13
• Mass number is 27
• Number of protons = 13
• Number of electrons is equal to number of protons = 13
• Number of neutrons = Mass number – Number of protons
• = 27 – 13
• Number of neutrons = 14 .
