4 Imagine that a new alkali metal has recently been discovered and that it
fits into the Periodic Table below francium. We will call this new element
edexcelium.
a Explain whether you would expect edexcelium to be more or less dense
than francium.
b State how many electrons edexcelium will have in its outer shell.
c State the names of the products that will be formed when edexcelium
reacts with water.
d Explain whether edexcelium will be more or less reactive than francium.
e If the symbol for edexcelium is Ed, write a balanced chemical equation
for the reaction of edexcelium with water.
f When edexcelium reacts with water, will the solution formed be acidic,
alkaline or neutral?
g Write the formula for the compound formed when edexcelium reacts
with air. helpz
