This is a very complex and interesting question, and it has kept scientists busy for a long time. As you mentioned, an atom has a central heavy part, or nucleus, around which electrons orbit, like the planets around the sun. But why do they orbit it? The first important thing to know is that electrons have an electrical charge. Electrons are negatively charged, while the nucleus is positively charged. You may have heard the phrase "opposites attract"; well this is certainly true for charges. An electron is pulled toward the nucleus by the electric force, just like planets are pulled to the sun by gravity.
OK, but why does the electron orbit, instead of just being pulled toward the nucleus and crashing into it? Think of it this way. Imagine you are coasting along on a skateboard at a constant speed, and you see something to your right that you are attracted to (maybe another boy or girl). You start to turn towards them, but your forward your motion will carry you past them. If the conditions are right, you'll keep turning, but your forward motion will keep making you miss them. You'll just circle them, always turning toward them, but never getting there. It's like that for the electrons (and planets, for that matter). They can't slow down, so they just keep turning and overshooting, forever circling the object of their desire. (Of course with a skateboard, you'll start to slow down, and you can spiral in to the object). This is only a tiny part of the story and it raises many further questions. Why is there an electrical attraction? What makes up the nucleus? Why doesn't the electron slowly lose speed and spiral down? Why is an electron moving in the first place? It is the way of science that every answered question leads to yet more questions!
but i dont know who found out about this sorry=(
What else can I help you with?
Do electrons move slow or fast around the nucleus?
Electrons move fast around the nucleus at speeds close to the speed of light. The exact speed of an electron is determined by its energy level and its distance from the nucleus.
What is the space called where the electrons move around the nucleus?
The space in which electrons move around the nucleus is called the electron cloud or electron shell. It represents the region where electrons are most likely to be found within an atom.
Do electrons and protons circle neutrons?
In an atom, electrons move around the nucleus, which contains both protons and neutrons. Protons and neutrons are found in the nucleus, while electrons move in orbitals around the nucleus. The orbits of electrons are complex and not necessarily circular.
The space surrounding the nucleus of an atom contains revolving?
Electrons. These electrons move in orbitals around the nucleus, which is the central part of the atom containing protons and neutrons. The arrangement of these electrons determines the chemical properties of the atom.
The space in which the electrons move is huge compared to the space occupied by the?
The space in which electrons move is huge compared to the space occupied by the atomic nucleus. Electrons are found in electron clouds that extend far beyond the nucleus, making up most of the volume of an atom. The nucleus, where the protons and neutrons are located, is very small in comparison.
Which parts of the atom move around the nucleous?
Electrons. They have a negative charge.
Is electrons found inside the nucleus?
They are not in the nucleaus, they orbit around the nucleus.
What part of the atom moves around the nucleus what type of charge do they have?
Electrons move around the nucleus of an atom. Electrons have a negative charge.
What does the electron move around?
Electrons move around the nucleus of the atom.
Are electrons on the outside?
Electrons move around the atomic nucleus.
Do electrons move slow or fast around the nucleus?
Electrons move fast around the nucleus at speeds close to the speed of light. The exact speed of an electron is determined by its energy level and its distance from the nucleus.
In physical science which particles move around the nucleus of an atom?
Electrons move around the nucleus of an atom. Protons and neutrons are located in the nucleus at the center of the atom. Electrons orbit the nucleus in specific energy levels, or shells.
What is around an atom's nucleus?
It is the electron cloud that surrounds the nucleus of an atom. The electrons move in their orbits around the nucleus, and they form the cloud.
How do electrons move across the nucleus?
Electrons spin around the nucleus, like the earth orbits the sun
What particle move around the nucleus?
electrons
Do electrons move around a nucleus?
Yes, electrons move around the nucleus of an atom in specific energy levels or orbitals. The movement of electrons is based on quantum mechanics and they can exist in a probabilistic cloud around the nucleus rather than following a fixed path.
What keeps electrons moving around the nucleus?
Electrons move around the nucleus due to the attractive force between the positively charged protons in the nucleus and the negatively charged electrons. This force, called electrostatic attraction, keeps the electrons in orbit around the nucleus.
