Particle Physics

They can also be called Lewis Dot Structures or Diagrams, named after a scientist names Gilbert Norton Lewis

Electrons

Arsekone

The cathode ray experiment helped discover electrons

To find the amount of protons in an atom, you simply look at the atomic number. For example, if the question was, "how many protons are in an atom of carbon", you look at the periodic table and see that carbon is the atomic number six, therefore your answer would be six.

Lead is a metal element. There are 82 electrons in a single atom.

Because it is missing the electronic configuration for 2p orbital.

When scientists say that quarks are elementary particles it means that they are NOT made up of other particles.

Yes, they can. In fact, they're absolutely necessary these days due to the energies needed to create them. There are two main labs in the world that focus on doing this. The first is the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany. The second is Lawrence Berkeley National Laboratory in Berkeley, California.

Electrons weigh in at about 9.1 x 10^-28 grams and protons about 1.67 x 10^-24 grams, making the proton about 1,837 times heavier than the electron. This is roughly about the same weight of a rabbit compared to an elephant.

Basically, atoms are made up of subatomic particles. Subatomic, sub- meaning smaller that, so subatomic particles means "a particle smaller than an atom". So It means that it is a particle within the atom.

If you have 92 protons and 108 neutrons you will get 200 electrons

The Higgs Boson is called the "God" particle because it would help explain on of physics biggest mysteries: how gravity works.

Can both God and the Higgs Boson exist? Yes, if God exists, then he could have created the Higgs Boson, like he created other particles.

as far as i know recoil means change in the momentum of a particale, either by collision with another particale or radiation interaction.

Yes, it's called an unoccupied orbital. There are actually infinitely many unoccupied orbitals for each atom. They represent possible solutions to the wave equation for the atom, and could potentially be occupied by an electron if the atom enters an excited state.

the video is about how e = E as you can see

Temperature is generally considered to be continuous. However, at the particle level of physics ,energy is believed to be made of discrete particles, so in actuality temperature may not be continuous but jumps in quantum amounts when temperature changes.

observable ? i'd say quarks.

Approximately 6.25E18 electrons in a Coulomb.

electromagnetic

The "strong nuclear" force, but this can only happen if there are also neutrons, as the "electromagnetic" force would usually repel two protons.

The troposhpere is thick (relatively speaking) with gases and so more high energy EM waves are absorbed before they can reach the ground.

You are PROBABLY referring to the "Bohr Model" of the atom.

All "Mercury" dimes (aka Winged Liberty Head Dimes) struck at the branch mints of Denver (D) and San Francisco (S) have their mint marks near the bottom of the reverse, just to the right of the word "ONE".
