Answer:
renewable energy sources such as solar and wind DONT emit carbon dioxide and other greenhouse gases that contribute to global warming
Explanation:
Transition metals will often violate the octet rule by using their d orbitals for bonding.
Answer:
The element is oxygen.
1s² 2s² 2p⁴
Explanation:
Let's consider the electron configuration of the excited state.
1s² 2s² 2p³ 3s¹
According to the Aufbau principle, the electron in 3s should occupy the shell with lower energy. The ground-state electron configuration is:
1s² 2s² 2p⁴
The differential electron is in the level 2. Then, the element is in the period 2.
The electrons in the last level are 2 + 4 = 6. Then, the element is in the group VIA or 16.
The element is oxygen.
I think the answer is a). While though peptides and proteins are formed by amino acids. But the proteins have more complex structure than peptided and this leads to the higher function of proteins over peptides.
