Lithium has an electron configuration of 1s2 2s1 and produces a red flame color
Lithium has an electron configuration of 1s2 2s1 and produces a green flame color
Lithium has an electron configuration of 1s1 and produces a red flame color
Lithium has an electron configuration of 1s2 2s1 and produces a blue flame color
Understanding the Answer
Let's break down why this is correct
Lithium’s atoms have two electrons in the 1s orbital and one in the 2s orbital. Other options are incorrect because The belief that lithium produces green light comes from mixing up sodium, which gives a yellow flame; Some think lithium only has one electron, forgetting the core 1s electrons.
