Answer:

X has 9 Electrons, 9 Protons and 10 Neutrons

X is Fluorine

Explanation:

19 in X is Nucleon number

So, if you minus 19 by 9 down there (which is proton number) you'll get 10 (Neutron number).

Now, Proton = Electron. That's why Electron is 9 too. I figured that X is Fluorine bcuz it has 9 Electrons. If you venture around in the periodic table, fluorine is the ninth element innit.

hope this helps ya \(^o^)/

r-ruslan [8.4K]
<h3><u>Answer;</u></h3>

Find the number of 1-foot cubes that fill the fish tank

<h3><u>Explanation;</u></h3>

Volume of a cuboid such as the fish tank is given by the product of length width and height;

Such that; Volume = length × width × height

Similarly, we can count the number of 1 foot cube that can fill the fish tank.

And since each cube has a volume of 1 cubic ft, then the number of cubes will be equivalent to the volume of the fish tank in cubic ft.
