Q1. Arrange these elements in increasing:

a. valence electrons

b. electronegativity values.

c. Ionization energy.

Q2. What do you notice with the number of valence electrons, electronegativity values and ionization energies of the elements?

Q3. What kind of element has the greatest tendency to attract electrons? Why?



Q2: the less valence electrons, the less electronegativity and ionization energy 
       the more"equals to more e and i energy
q3: metals because nonmetals and noble gases have low ionisation energies
