- 1Which in the following list is a metal? a. lithium b. nitrogen c. fluorine d. carbon e. oxygena. lithium
explanation: lithium is in the alkali metal list which is on the far left side of the periodic table found in group 1/1A - 2When someone talks about an element in the Chalcogen group, which element are they talking about? a. lithium b. carbon c. nitrogen d. oxygen e. fluorined. oxygen
explanation: oxygen is in the chalcogen group which is on the right side of the table in group 16/6A - 3Which atomic orbital is lower in energy than 2s? a. 1s b. 1p c. 2p d. 3sa. 1s
ex) 1p orbital is not a possible orbital designation. 2p and 3s orbitals are higher in energy than 2s. Therefore, 1s orbital is the answer and is lower in energy than 2s. - 4If an electron “travels” from a higher energy to a lower energy state, Fluorine: 1s22s22p5 Sodium: 1s22s22p6 Neon: 1s22s22p63s1 Scandium: 1s22s22p63s23p64s3Fluorine
ex) - 5What is the maximum number of electrons can you put into one of the 4d orbitals? a. 1 b. 2 c. 6 d. 10 e. 14b. 2
Explanation: Any atomic orbital, regardless of type of orbitals, can only accommodate up to 2 electrons. Therefore, the answer is 2. - 6Which of the following has most electrons?
