Match each of the questions below with either "True" or "False" as appropriate.
-The metals with the highest ionization energies are most likely to be found in nature in the elemental state.
- Metals usually have higher melting points than nonmetals.
- Co(II) ion in water is blue.
- The electron configureation of Mn2+ is [Ar]4s23d3.
- All tetrahedral complex ions are high spin.
My answers are:
1.False
2.True
3.True
4.False
5.False
Please answer back if I might have something wrong...
Would you please go through and tell us why you think each answer is as you have it.
-The majority of metals are not naturaly made...so that is why the first one is false.
-Metals have higher melting points than nonmetals because the electrons are tightly pack into a solid form and is a fact in the book.
-Is true because I found it in a website but I can't post it because I don't own it.
-Is false because when is a + ion you subtract not add...so that is why it makes it false.
-This one I am not really sure because spining pairs are very tricky...so this is really confusing
It seems like you have a good understanding of some of the questions, but there are a few points that can be clarified. Let's go through each question individually and provide explanations for each answer.
1. The metals with the highest ionization energies are most likely to be found in nature in the elemental state.
Your answer: False
Explanation: This statement is true. Metals with high ionization energies tend to form stable compounds with other elements rather than existing in the elemental state in nature. High ionization energy indicates that it is difficult to remove an electron from a metal atom, making it less likely to exist as a free element.
2. Metals usually have higher melting points than nonmetals.
Your answer: True
Explanation: You are correct. Metals generally have high melting points because they have strong metallic bonds between the positively charged metal ions and the delocalized electrons. These strong bonds require a significant amount of energy to break, resulting in higher melting points compared to nonmetals.
3. Co(II) ion in water is blue.
Your answer: True
Explanation: This statement is true. The Co(II) ion, also known as cobalt(II) ion, typically appears blue in water. The color arises due to the absorption of specific wavelengths of light by the ion.
4. The electron configuration of Mn2+ is [Ar]4s23d3.
Your answer: False
Explanation: The electron configuration of Mn2+ ion is [Ar]3d5. When an ion is formed, electrons are typically removed from the highest energy level first. In this case, two electrons are removed from the 4s orbital, leaving behind the electron configuration [Ar]3d5.
5. All tetrahedral complex ions are high spin.
Your answer: False
Explanation: This statement is false. The spin state of a complex ion depends on various factors such as ligand field strength and electron configuration. While some tetrahedral complexes may exhibit high spin, others can have low spin configurations depending on the specific ligands and electronic structure involved.
Based on the explanations provided, it appears that your answers for questions 1, 2, 3, and 4 are correct. However, the answer for question 5 is incorrect. Not all tetrahedral complex ions are high spin; it depends on the specific complex and its electronic configuration.
