Answer: An atom is the sub-component of a molecule, or the smallest unit of matter. It is the smallest part an element can divide into. A molecule is made up of atoms that are bound by ionic, covalent or metallic bond.
The final volume of the balloon is 84.75 ml
<u><em>calculation</em></u>
The volume is calculated using Charles law formula
that is V1/T1= V2/T2 where,
V1= 5.00 x10^2 ml
T1= 22.0 °c into kelvin = 22 + 273 = 295 K
V2= ? ml
T2 =0.500 x 10^2 K
make V2 the subject of the formula by multiplying both side by T2
V2 is therefore = T2V1/T1
V2 = (0.500 x 10^2 K x 5.00 x10^2 ml) / 295 K = 84.75 ml
Answer: The Pauli Exclusion Principle
Explanation:
The electrons are filled in orbitals of equal energy with one electron entering each orbital until all the orbitals contain one electron with the same spin. The pairing of electrons take place thereafter.
The first electron in an orbital could have +1/2 spin or -1/2 spin. All of the electrons in singly occupied orbitals have the same spin so as to maximize total spin. which is given by Hunds rule.
Two electrons must have opposite spin and thus different spin quantum numbers is given by Pauli's exclusion principle.
