ANSWER THESE ASAP 1. What are the three subatomic particles in an atom and where are they found?

2. Why is the model that depicts electrons going around the nucleus like a planet, wrong?

3. How can we identify an element?

4. If you are looking at the periodic table in the video. What is the element with the atomic number of 19?

5. In the video you see that they drew a model of a Carbon atom. What would a model of an Oxygen atom look like? In other words, how many protons, electrons, and neutrons will you draw, and the location of each subatomic particle.

Explanation:

1.Proton,Electron and Neutron.

Protons and Neutrons are located inside of the nucleus and atoms are left outside of the nucleus.

2.Sorry can't help you with this one but give me more information and I could help.

3.Using a periodic table let's you find out what they are.

4.Dunno what video you were watching but I'm guessing it's potassium and the symbol or letter is K for 19 on the periodic table.

5. In a oxygen atom the atomic number is 8, per shell there is 2,6( two located closest to the nucleus(inner shell) while the other 6 on the outside(outside shell).

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
