a) Other than their location in the atom, name two other differences between an electron and a proton.
b) The table below gives the number of electrons, protons and neutrons in particles
A, B, C, D, E, F and G.

i) Which particle is likely to be a halogen?
ii) What is the mass number of E?
iii) Write a formula of the compound formed when E combines with G.
iv) Name the type of bond formed in (iii) above.
v) How does the radii of C and E compare? Give a reason.
vi) Draw a dot (.) and cross (x) diagram for the compound formed between A and F
vii) Why would particle B not react with particle D?

Answers

a)i) Electrons are negatively charged while protons are positively charged


ii) Electrons have neglible mass while protons have significant mass (1 a.m.u)


b) i) F


ii) 13 + 14 = 27

iii) E₂G₃

iv) Ionic bond.

v) E has a small atomic radius than C. This is because E has greater nuclear charge hence its electrons
are pulled strongly.
