Which element in group 1 has the greatest tendency to lose an electron

Fr has the greatest tendency to lose an electron. Electronegativity, which is an elements tendency to gain an electron, decreases as you go down a group, meaning that an element’s tendency to lose an electron increases as you go down a group. This means that the element in group 1 with the lowest electronegativity (the element at the bottom of the group), Fr, the element with the greatest tendency to lose an electron.

The velocity would be 2 

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
