1.Element 'X' contains 9 protons, 10 electrons and 11 neutrons. What is 'X'?
2.Sulphur has an atomic number of 16 and a mass number of 32. State the number of protons and neutrons present in the nucleus of sulphur.
Answer:
Protons → Atomic number = 16 = P
Number of Neutrons = A – P = 32 – 16 = 16
3.Give a simple diagram to show the arrangement of the electrons in an atom of sulphur.
Answer:
In sulphur atom.
Number of electrons = P = e = 16
Elements X, Y, Z have atomic numbers 6, 9 and 12 respectively. Which one :
forms anion – negative ion ;
forms cation – positive ion ;
has 4 electrons in the outermost orbit. [Y, Z, X]
Answer:
Atomic number of
X = 6 = number of electrons (2, 4)
∴ X has 4 electrons in outermost orbit.
Y = 9 = number of electrons (2, 7)
∴ Y form anion = negative ion
Z = 12 = [2, 8, 2]
∴ Z forms cation – positive ion.
