I JUST NEED HELP Which group or groups of atoms are the only atoms with f orbitals?
Question 10 options:

A)

All noble gases

B)

All atoms heavier than barium (Ba)

C)

All atoms heavier than krypton (Kr)

D)

Lanthanides and actinides

All atoms heavier than barium (Ba)

arium has completely filled 5d orbitals and 6s orbitals. After barium, the lanthanide elements occur, in which inner shell 4f-orbitals are filled. So all atoms heavier than Ba possess f-orbitals.

Explanation:

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
