QuestionIdentify the brittle element that is a poor conductor and prefers a -2 charge in compounds: (A) Cl (B) Au (C) Si (D) Al (E) S.
Studdy Solution
STEP 1
Assumptions1. We are looking for an element that is brittle.
. The element is an extremely poor conductor of heat and electricity.
3. When the element exists as an ion in a compound, it prefers to have a charge of -.
STEP 2
Let's analyze each option based on the given criteria.
(A) Chlorine is a halogen, which is a poor conductor of heat and electricity. However, it prefers to have a charge of -1 when it is an ion, not -2.
(B) Gold is a metal, which means it is not brittle and is a good conductor of heat and electricity. It does not meet any of the criteria.
(C) Silicon is a metalloid, which means it is not brittle and can conduct heat and electricity to some extent. It also does not prefer to have a charge of -2 when it is an ion.
(D) Aluminum is a metal, which means it is not brittle and is a good conductor of heat and electricity. It also does not prefer to have a charge of -2 when it is an ion.
(E) ulfur is a nonmetal, which means it is brittle and a poor conductor of heat and electricity. It prefers to have a charge of -2 when it is an ion.
STEP 3
Based on the analysis, the element that meets all the criteria isulfur ().
