Good job
The chemical symbol for chlorine is Cl. There are seven valence electrons present in chlorine.
What are valence electrons?
Valence electrons are electrons in an atom's outermost shell, or energy level. For example, oxygen contains six valence electrons, two of which are in the 2s subshell and four of which are in the 2p subshell.
The chemical symbol of the element (as found on the periodic table) is written in the Lewis symbol for an atom, and the valence electrons are depicted as dots encircling it.
The number of electrons in an atom's outermost shell is referred to as its valence electrons. The final shell of the chlorine atom now has 7 electrons. As a result, a chlorine atom contains 7 valence electrons.
Therefore, Cl is the chemical symbol for chlorine. In chlorine, there are seven valence electrons.

if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?
Answer:
The earthworm will be 45 mm long in the picture
Explanation:
From the problem, we can take the original size of the earthworm to be 18mm.
Magnification can be obtained using the formula:
magnification = observed size/ original size.
Recall, we are given that the magnification is 2.5.
Hence, can evaluate the size in the picture to be
2.5 X 18mm = 45mm
