So you do not usually have one isotope changing into another isotope of the same element. So, it is not possible to give you a general answer other than to say that the isotopes of an element form in one or more of the above ways, but each isotope of an element may or may not form in a similar way as other isotopes.Įxcept as listed above, an atom that is not radioactive never changes its number of neutrons. There are a few other ways, but they are not all that significant.Įach isotope (more properly called a nuclide) has its own way(s) in which it is formed. Being changed from one type of atom to another by high energy nuclear reactions, such as having a neutron slam into the nucleus at an extremely high velocity. Because the protons and electrons have the same value of charge.With the exception of the hydrogen and helium that were formed shortly after the Big Bang event, elements mainly form in the following ways:Ĥ. It's equal into so manyĮlectrons or so many protons. And we also saw that oneĬoulomb, how big a Coulumb is. We saw what the charge on theĮlectrons and the protons are. Learned in this video, is the unit for electricĬharge is Coulombs. That's how I like to thinkĪbout what one Coulumb is. You take so many electrons together, that itself represents what a Coulumb is. And so when I went to ask myself, how big is a Coulomb? I like to think of it as one Coulumb is equal than to so many electrons. So anyways, these many electrons such a huge number 10 to the 18 electrons, these many electrons together make up a charge of negative one Coulomb. Write it in proper note to be 6.25 x 10, to So to get one Coulumb worth of charge, we need so many electrons, so many and of course we can also And that so many electrons is equivalent to now a charge of negative one Coulomb.
PROTON CHARGE QUANTITY PLUS
Left-hand side, 0.625 that's one divide by 1.6, and this will become 10 xġ0 to the power plus 19, plus 19. Let's bring in my calculatorĪnd see what that gives me. Left-hand side as well by 1.6 times 10 to the power minus 19. So that this will cancel andīecome negative one Coulomb. Let's divide the right-hand side by 1.6 x 10 to the minus 19. Hand side one Coulomb, I will divide the right-hand side. We're dealing with, it would be negative. We know one electron is worth a charge of 1.6 x 10 to the minus 19 Coulombs. So to do this, we know one electron, so let's write that down. Using this information try to figure this out yourself first. How many electrons together make up a negative one Coulomb worth of charge? So, great idea to pause the video first and see if you can try But exactly how much, is the question So let's think about this. So it's gonna be a huge number because charge on each electron is so tiny we need a lot of electrons How many, say electrons would make up a total On an electron or a proton is such a small number, for electrons it would be negative, for protons it would be positive. Have some sense for what or how big a Coulumb would be. Sense for what a kilogram is or how big one meter is, it would be great to It would be nice if weĬould get some sense for how big it is. Nelson's Coulomb is aīrand new unit for us. So, so many Coulombs is the charge on an electron or a proton. Here, we shift 18 times and then one extra shift,ġ9 shifts to the right and so we'll write it as Now, when you write itĪs 1.6 x 10 to the power, now let's see how many, how many times we have shifted it. So we will shift thisĭecimal all the way to here. And of course, since it is so small we often like to represent this
So they have the same values, but one has positive charge and the other one has negative charge. So the electron has this muchĬharge, but it's negative. Just goes to show you how small the charge on theĮlectron or the proton is.
And the number of zeroes over here are 18. I can't write them all zero one six and some Let's see, we write it as 0.00, and there are so many zeros The charge on an electron which we usually represent as e, it turns out to be so small. Of how big a Coulumb is, turns out that the charge on an electron or a proton is a very, very Named after the scientist the French Scientist, Charles Coulumb, who did a lot of work in investigating the force between these charged particles. Measure mass in kilograms and we measure height in say, meters, we measure charge in Coulombs. So the symbol for theĮlectric charge is q. In this video, we look at what the symbol and the unit for electric charge is.
We call this "The Electric Force." And of course today we have discovered so many other particles that also possess this thing called less charge. Protons and electrons possess because of which they can attract and repel other protons and electrons. Previous video we discussed what Electric Charge is.
