hello well here we are last units of natural science okay it's called electricity
00:00:00
electricity is energy that occurs as a result of charged particles but to understand it better
00:00:09
to understand how it works we need to understand atoms all matter toda la materia is made up of
00:00:15
atoms. Anything, a book, a computer, the window is made up of a lot of atoms.
00:00:23
Here you are the atoms. They have a nucleus, you can see, and these blue particles are the
00:00:32
electrons and they can move outside the atom. We represent them as in your book,
00:00:41
in red in green and blue let's see in the nucleus there are protons with
00:00:49
positive electric charge okay positive then also in the nucleus there are
00:00:57
neutrons with no electric charge and outside in blue the most interesting one
00:01:04
for these units electrons with a negative electric charge they move
00:01:10
around the nucleus, all right? They are not in like protons and neutrons. An atom
00:01:15
is electrically neutral when it has the same number of protons and electrons. If
00:01:23
it got five protons and five electrons we say it's electrically neutral. But if
00:01:29
you wrap two objects together, electrons can move from one atom to another, which
00:01:35
makes the objects electrically charged remember electrons the blue ones outside
00:01:42
okay this means when an atom gains electrons and have more electrons than
00:01:48
before and the atom has more electrons than before it becomes negatively
00:01:56
charged however when an atom loses electrons it becomes positively charged
00:02:01
Positive and negative charges attract each other, okay, like magnets. Positive
00:02:07
charges repel all the positive charges, negative charges repel all the negative
00:02:14
charges. Here you are in the picture, they don't like staying with the same. And, well,
00:02:19
the charged particles result in electricity. Here we are. To sum up, atoms. We
00:02:25
gets three types three particles inside the atoms okay all the atoms have
00:02:32
protons neutrons and electrons protons positive electric charge they attract
00:02:38
electrons they repel the protons they repel all the protons and they are in
00:02:46
the nucleus the neutrons no electric charge nothing remember they are in the
00:02:52
nucleus like the protons and electrons have a negative electric charge they
00:02:57
protons, they repel other electrons and they are outside the nucleus. Is it clear
00:03:02
now? Finally, what is electricity again? Electricity is energy that occurs as the
00:03:10
result of charges particles. I hope you understand good, that's it, so if you have
00:03:17
any questions always ask and please do your activities to practice better. See
00:03:23
you soon, goodbye!
