Free_Kalibri [48]

3) Answer is: because elements have different emmision spectrum.

Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state. Each element's emission spectrum is unique.

4) Answer is: lithium chloride and sodium chloride do not have similar colors.

Lithium ion has red and sodium ion has yellow emission spectrum.

5) Answer is: because metals have valence electrons in different energy shells.

Each transition has a specific energy difference.

6) Answer is: salts of alkaline and earth alkaline metals.

For example barium chloride gives green light.

Why do plant animal cells both have mitochondria?
LuckyWell [14K]

This element has 3 electrons in its Lewis dot structure and is in the 3p orbital section.
Lynna [10]
The answer is Al. If it is a main group element with 3 electrons in its Lewis dot structure, it must be in group 3A. If it is in the 3p orbital section, then it must be in period 3, since the p orbital is a valence orbital and the number that preceeds it is the principal quantum number. Therefore, your answer is the element in period 3 and group 3A, which is aluminum.
