New cards

Density formula

d = m/v

  • density directly proportional to mass

2
New cards

trend of atomic volume and atomic mass across period

volume = left to right > decrease

mass = left to right > increase

3
New cards

Since mass increase across period

density does too

4
New cards

order of density in group

3d < 4d<< 5d

5
New cards

Maximum density

Ir slightly greater, almost equal to Os

6
New cards

Cu>Zn

Zn has lower density because of its large atomic volume

7
New cards

Ionization energy

Higher IE than group 1 and 2 due to high Zeff

8
New cards

IE1 of Zn,Cd,Hg

very hugh cuz fully filled
