Gaaffii 1

According to valence bond theory. Which orbitals on bromine atoms overlap in the formation of the bond in Br2\mathrm{Br_2}?

  1. A.3s
  2. B.3P
  3. C.4s
  4. D.4P
Deebii fi ibsa ilaalaa

Deebii: D 4P

Maaliif

Bromine has the valence electron configuration 4s² 4p⁵, so each bromine atom has one half-filled 4p orbital that overlaps with the other to form the single covalent bond in Br₂.

Gaaffii 2

The type of compound that is most likely to contain a covalent bond is one that is

  1. A.A solid metal
  2. B.Composed of only non-metals
  3. C.Composed of a metal from the far left and a non-metal from far right of the periodic table
  4. D.Held together by the electrostatic forces between oppositely charged ions.
Deebii fi ibsa ilaalaa

Deebii: B Composed of only non-metals

Maaliif

Covalent bonds form primarily between non-metal atoms through the sharing of electron pairs, whereas bonds between metals and non-metals are typically ionic.

Gaaffii 3

The first step of the scientific method involves

  1. A.Forming a hypothesis
  2. B.Making observations.
  3. C.Performing an experiment.
  4. D.Predicting the result of an experiment
Deebii fi ibsa ilaalaa

Deebii: B Making observations.

Maaliif

The scientific method typically begins with making observations about a phenomenon, which then leads to asking questions and formulating a hypothesis.

Gaaffii 4

The process of solute particles being surrounded by solvent particles is known as

  1. A.Saturation
  2. B.Agglomeration
  3. C.Solvation
  4. D.Dehydration
Deebii fi ibsa ilaalaa

Deebii: C Solvation

Maaliif

Solvation is the process in which solute ions or molecules are surrounded and stabilized by solvent molecules (called hydration when the solvent is water).

Gaaffii 5

Which one of the following represents an acceptable possible set of quantum numbers (in the order n, l, mlm_l, msm_s) for an electron in an atom?

  1. A.2, 1, 0, 0
  2. B.2, 0, 2, +1/2
  3. C.2, 1, -1, 1/2
  4. D.2, 0, 1, -1/2
Deebii fi ibsa ilaalaa

Deebii: C 2, 1, -1, 1/2

Maaliif

For n = 2, l can be 1, ml can range from -1 to +1 (so -1 is allowed), and ms can be +1/2. The other options violate quantum number rules: spin cannot be 0 (A), and when l = 0, ml must be 0 (B and D).

Gaaffii 6

Of the three types of radioactivity characterized by Rutherford, which of the following are particles?

  1. A.γ\gamma - rays
  2. B.β\beta - rays
  3. C.α\alpha - rays and β\beta - rays
  4. D.α\alpha - rays, β\beta - rays, and γ\gamma - rays
Deebii fi ibsa ilaalaa

Deebii: C α\alpha - rays and β\beta - rays

Maaliif

Alpha rays (helium-4 nuclei) and beta rays (high-speed electrons) are particle radiation, whereas gamma rays are high-energy electromagnetic waves.
