o a groups 3a through 8a
b groups 1a and 2a
o c transition metals
d inner transition metals

question 27 (1 point)
which of the following elements is a transition metal?
o a copper
b cesium
o c tin
d tellurium

question 28 (1 point)
which of the following is true about the electron configurations of the representative elements?
o a the electrons with the highest energy are in a d sublevel.
o b the electrons with the highest energy are in an f sublevel.
o c the highest occupied s and p sublevels are partially filled.
o d the highest occupied s and p sublevels are completely filled.

Explanation:

• Question 26:
• Groups 1A and 2A have their highest - energy electrons in \(s\) orbitals.
• Transition metals have their highest - energy electrons in \(d\) orbitals.
• Inner transition metals have their highest - energy electrons in \(f\) orbitals.
• Groups 3A - 8A (also known as the p - block elements) have their highest - energy electrons in \(p\) orbitals.
• Question 27:
• Cesium (\(Cs\)) is an alkali metal (Group 1A), tin (\(Sn\)) is a p - block element (Group 4A), tellurium (\(Te\)) is a p - block element (Group 6A).
• Copper (\(Cu\)) is in the d - block and is a transition metal.
• Question 28:
• Representative elements (Groups 1A - 8A) have their highest - energy electrons in \(s\) and \(p\) orbitals.
• For representative elements (except noble gases), the highest - occupied \(s\) and \(p\) sublevels are partially filled. Noble gases (Group 8A) have completely filled \(s\) and \(p\) sublevels, but they are also considered representative elements in some classifications. However, the general rule for representative elements (excluding noble gases) is that the highest - occupied \(s\) and \(p\) sublevels are partially filled.

Answer:

• Question 26: a. groups 3A through 8A
• Question 27: a. copper
• Question 28: c. The highest occupied \(s\) and \(p\) sublevels are partially filled.
