No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise

Explanation:
the correct electron-dot formula for a molecule of chlorine?
Answer:
Cl has 7 dots
if its Cl2; Cl-Cl it will contain 14 dots
Explanation:
The electron-dot formula of the chlorine molecule Clâ‚‚is shown in the attached diagram below.
What is the lewis electron dot diagram?A lewis electron dot structure is used to represent the number of bonds, the bonding atoms, and the lone pairs left in the atoms in the molecule.
Lines are shown between atoms that are bonded to one another and excess electrons or lone pairs are represented as dot pairs and are placed next to the atoms.
As the valence electrons of each chlorine atom are equal to seven from the electronic configuration of the chlorine atom.
First, the total number of valence electrons in a chlorine molecule is 7 + 7 = 14.
As each chlorine atom needs only one electron to complete its octet. As the octet completes, the rest of the electrons are assigned as the lone pairs of atoms. Therefore, each chlorine atom has three lone pairs of electrons on it.

What is the difference between magnetic stripping and magnetic field reversal?
You place 12.0 milliliters of water in a graduated cylinder. Then you add 15.0 grams of metal to the water and the new water level is 13.91 milliliters. What is the density of the metal in grams per milliliter?
Answer:
The answer is 7.85 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
volume = final volume of water - initial volume of water
volume = 13.91 - 12 = 1.91 mL
We have
[tex]density = \frac{15}{1.91} \\ = 7.853403141...[/tex]
We have the final answer as
7.85 g/mLHope this helps you
Answer:
Hello, Im Mack :)
Here is the Correct Solution for your question:
Answer is 7.85 g/mL
Explanation:
The density of a substance can be found by using the formula
-volume = final volume of water - initial volume of water
-volume = 13.91 - 12 = 1.91 mL
-Final Answer is: 7.85 g/mL
