Consider the following information about the newly discovered element, vulcium, whose symbol is Vu. ‘Vulcium is a solid at room temperature. It is easily cut by a penknife to reveal a shiny surface which tarnishes quite rapidly. It reacts violently with water, liberating a flammable gas and forms a solution with a pH of 13. When vulcium reacts with chlorine, it forms a white crystalline solid containing 29.5% chlorine.’ (Ar: Vu = 85)

a. Calculate the empirical formula of vulcium chloride.

b. To which group of the Periodic Table (p. 136) should vulcium be assigned?

c. Write a word and balanced chemical equation for the reaction between vulcium and chlorine.

d. What other information in the description supports the assignment of group you have given to vulcium?

e. What type of bonding is present in vulcium chloride?

f. Write a word and balanced chemical equation for the reaction between vulcium and water.

g. Write the formulae for:

(i) Vulcium sulfate

(ii) Vulcium carbonate

(iii) Vulcium hydroxide.

Look at the Periodic Table to find out the real name of vulcium.
