Things that are shocking that I just remembered Flashcards
1
Q
Can all elements produce line spectrum?
A
just gasses
2
Q
if hydrogen has only one electron, why does it produce multiple lines on emission specturm
A
because there are many unseen energy levels which the electron can jump to, then fall back down creating several different lines
3
Q
why is akline metals more reactive the all the other groups
A
because they have the lowest Ionization energy because of their low amounts of protons and they want to form a cation therefore because there is a low IE they are more likely to react making them more reactive
4
Q
what element has highest IE
A
helium
5
Q
what is a half life
A
time it takes for half a sample of radioactive atoms to decay into stable nonradioactive atoms
