Gaaffii 1

Which model of an atom describes an atom as a positive sphere where electrons are embedded in a sphere?

  1. A.Ernest Rutherford
  2. B.J.J. Thomson
  3. C.Neil's Bohr
  4. D.John Dalton
Deebii fi ibsa ilaalaa

Deebii: B J.J. Thomson

Maaliif

J.J. Thomson proposed the plum pudding model of the atom, which describes the atom as a sphere of positive charge with negatively charged electrons embedded within it, like raisins in a pudding.

Gaaffii 2

An element X has two stable naturally occurring isotopes (816X^{16}_{8}X & 818X^{18}_{8}X). If the average atomic mass of element X is 16.2 a. m. u. what is the percentage abundance of 816X^{16}_{8}X ?

  1. A.90
  2. B.25
  3. C.10
  4. D.75
Deebii fi ibsa ilaalaa

Deebii: A 90

Maaliif

Using the average atomic mass formula: 16.2=16x+18(1−x)16.2 = 16x + 18(1 - x), we solve for xx (the fractional abundance of 816X^{16}_8X) to get x=0.90x = 0.90, which corresponds to a 90%90\% abundance.

Gaaffii 4

Which of the following property decreases across a period of the periodic table?

  1. A.Ionization energy
  2. B.Atomic size
  3. C.Effective nuclear charge
  4. D.Electron affinity
Deebii fi ibsa ilaalaa

Deebii: B Atomic size

Maaliif

Atomic size decreases across a period because the effective nuclear charge increases, which pulls the outer electrons closer to the nucleus.

Gaaffii 5

Unequal distribution of the shared electrons between two atoms results in the formation of -

  1. A.Polar covalent bond
  2. B.Non-polar covalent bond
  3. C.Electrovalent bond
  4. D.Co-ordinate covalent bond
Deebii fi ibsa ilaalaa

Deebii: A Polar covalent bond

Maaliif

A polar covalent bond is formed when there is an unequal sharing of electrons between two atoms with different electronegativities, leading to partial charges.

Gaaffii 6

Which of the following is non-polar molecule?

  1. A.NH₃
  2. B.HF
  3. C.CCl₄
  4. D.SO₂
Deebii fi ibsa ilaalaa

Deebii: C CCl₄

Maaliif

CCl4CCl_4 has a highly symmetrical tetrahedral geometry where the individual polar C−ClC-Cl bond dipoles cancel each other out, making the overall molecule non-polar.

Gaaffii 7

According to Boyle’s law, doubling the pressure of a sample of gas, what will be the volume of gas at constant temperature?

  1. A.Doubled
  2. B.Tripled
  3. C.Halved
  4. D.One third
Deebii fi ibsa ilaalaa

Deebii: C Halved

Maaliif

According to Boyle's law, pressure and volume are inversely proportional at constant temperature (P1V1=P2V2P_1V_1 = P_2V_2), so doubling the pressure halves the volume.
