SAT Subject Test

Each of the following questions consists of two statements, I in the left-hand column and II in the right-hand column. For each question, determine whether statement I is true or false and whether statement II is true or false. Select the appropriate answer combination from the choices below. Choices with a filled CE oval denote that statement II is a correct explanation of the true statement I.

An element that has the electron configuration 1 s to the power of 2 end exponent invisible times 2 s to the power of 2 end exponent invisible times 2 p to the power of 6 end exponent 3 s to the power of 2 end exponent invisible times 3 p to the power of 6 end exponent invisible times 3 d to the power of 3 end exponent invisible times 4 s to the power of 2 end exponent is a transition element
BECAUSE
in atoms of transition elements, the 1 s, 2 s, 2 p, 3 s, and 3 p orbitals are completely filled in the ground state.

The figure shows a sample answer grid for question number one hundred one. Option (A) shows the sample answer grid that has a true and a false bubble option for the Roman numeral I statement, a true and false bubble option for the Roman numeral II statement, and a single bubble option for C E. For the Roman numeral I statement the true bubble is filled in, for the Roman numeral II statement the true bubble is filled in, and the C E bubble is filled in.

Correct Answer: 
No

Option (E) shows the sample answer grid that has a true and false bubble option for the Roman numeral I statement, a true and false bubble option for the Roman numeral II statement, and a single bubble option for C E. For the Roman numeral I statement the false bubble is filled in, for the Roman numeral II statement the false bubble is filled in, and the C E bubble is NOT filled in.

Correct Answer: 
No

The correct answer is T, T.

The element with the electron configuration shown is vanadium (atomic number = 23). The transition elements are those in groups 3-12 (or groups text IIIB end text minus text IIB end text, depending on how a particular periodic table is labeled). Therefore, statement text I end text is true. It is also true that the  1 s, 2 s, 2 p, 3 s, and 3 p orbitals are completely filled in the transition elements. However, statement text II end text is not a correct explanation of statement text I end text. For example, statement text II end text is true for text Ar end text, text Kr end text, text Xe end text, text end text text Rn end text, and other elements that are not transition elements.
