Solution Steps

Step 1: Determine the Valence of Oxygen

The valence of an element is typically determined by the number of electrons in its outermost shell that can participate in forming chemical bonds. Oxygen is in Group 16 of the periodic table and has six valence electrons. It typically forms two bonds to complete its octet, giving it a valence of 2.

Step 2: Determine the Valence of Bromine

Bromine is in Group 17 of the periodic table and has seven valence electrons. It typically forms one bond to complete its octet, giving it a valence of 1. This matches the provided answer.

Step 3: Determine the Valence of Tellurium

Tellurium is also in Group 16 of the periodic table, like oxygen, and has six valence electrons. It can form up to six bonds in certain compounds, giving it a valence of 6.

Final Answer

  1. The valence of oxygen is \(\boxed{2}\).
  2. The valence of bromine is \(\boxed{1}\).
  3. The valence of tellurium is \(\boxed{6}\).

The Lewis representation above depicts a reaction between hydrogen (blue) and a main-group element from group (red). In this representation, each Y atom needs electron(s) to complete its octet, and gains these electrons by forming bond(s) with atoms of H. There are unshared electron pair(s) and bonding electron pair(s) in the product molecule. The bonds in the product are .
