It's convenient with the atomic model to think of electrons having a certain amount of energy. The amount of energy is quantized, and each orbital has a specific amount of energy associated with it. To go to a lower energy level or orbital an electron would have to give up energy; to get to a higher energy level they would have to absorb a certain amount of energy. Since the nucleus with its positive charge attracts negatively charged electrons it takes work (added energy) to move them away from it. A simplistic view of why they don't collide with the nucleus is that they have too much energy to just spontaneously fall into the nucleus, and that the orbital they occupy is stable in terms of its spatial extents, which do not coincide with the location of the nucleus.
What else can I help you with?
Will the electrons in the higher energy level comes near the nucleus while they are revolving in their own orbit?
No, electrons in higher energy levels do not come closer to the nucleus while orbiting. In Bohr's model, each energy level corresponds to a specific orbit or distance from the nucleus, and the electrons remain in those orbits without spiraling inward. Energy levels represent the average distance of the electron from the nucleus rather than a physical path.
The paths in wich electrons circle the nucleus according to the Bohr model?
In the Bohr model, electrons circle the nucleus in specific orbits or energy levels, each with a fixed radius and energy value. These orbits are quantized, meaning electrons can only exist in certain stable orbits without radiating energy. The model's main idea is that electrons move in circular orbits at fixed distances from the nucleus, similar to planets orbiting the sun.
Electrons move about the nucleus of an atom in the same way that of as what?
the atmosphere moves around the planet Earth. If you still believe in the Bohr atom, that was revised a century ago. We now know that electrons are NOT like little planets in orbit around a nucleus playing the role of the sun, they are more like clouds, they surround the atomic nucleus without actually orbiting around it, as a cloud. Electrons can have any location and any size and shape that the electrostatic forces give them.
When the number of protons and electrons are the same the atom is neutral?
Yes, that is correct. An atom is neutral when the number of protons in the nucleus (positive charge) is equal to the number of electrons orbiting around the nucleus (negative charge), balancing out the overall charge to zero.
Surrounded the nucleus of an atom?
Ok, I think you mean electons. The nucleus is made up of protons and neutrons, surrounded by electrons. An electron has a negative charge. It is so light, it has negligible mass. The atom Hydrogen has only one proton as its nucleus, surrounded by its one electron. Oxygen has, of the top of my head, 8? electrons. These electrons move in orbitals around the proton. Without going into complicated detail, that's all I can tell you I'm afraid.
What is the Basic structure of an atom?
Basically, an atom consists of a very tiny nucleus surrounded by electrons. To understand the basic structure of an atom, you really need to know that the nucleus and electrons have opposite electrical charges. The nucleus is positively charged, and the electrons are negatively charged. Opposite charges attract; this is why the electrons stay bound to the nucleus. If there are an equal number of negative (electron) charges as there are positive charges in the nucleus (which come from the protons in the nucleus), the atom will will have no charge. The nature of the electron states is addressed by quantum mechanics. Electrons have wave properties. Without getting too deeply into the quantum theory, quite a lot about atoms and their properties can be rationalized using the Bohr model of the atom.
Why scientist concluded that electrons revolve around nucleus and not neutrons?
The amount of experimental data relating to the relative location of protons, neutrons, and electrons in an atom is so vast that it would be difficult to know where to start. It is known that protons and neutrons attract each other by means of the strong nuclear force; without this attraction it would be impossible to have any atom with more than one proton in the nucleus, since protons repel each other. This requires neutrons to be in the nucleus, with the protons, not orbiting the nucleus. When atoms are ionized, we know they lose or gain electrons and not neutrons because they acquire an electric charge. There are thousands of other ways of confirming this.
What is the difference between Bohr model and the electron cloud model?
Bohr's model depicts electrons in orbit around the nucleus. the electron cloud model shows orbitals within which an electron most likely is at any given time (the movement of electrons are random, and sometimes they get out of their orbital...i'm not making this up!). the electron cloud model is more accurate because electrons move closer and farther away from the nucleus, while the bohr model shows them at a given radius at all times.
Where are the electrons found in bhors atomic model?
In Bohr's atomic model, electrons are found in specific, quantized orbits or energy levels around the nucleus of an atom. These orbits are circular paths where electrons can exist without radiating energy. The distance of each orbit from the nucleus corresponds to a specific energy level, with higher energy levels being farther from the nucleus. Electrons can move between these orbits by absorbing or emitting energy, typically in the form of photons.
Describe and name the parts of an atom?
Constituents of the atom:In the NUCLEUS:PROTONS - positively chargedNEUTRONS - neutrally chargedOrbiting the nucleus:ELECTRONS - negatively charged
How does the current model of the atom differ from J.J. Thomson's?
J.J. thomson's model doesn't have an electrons flowing around like how are planets orbit the sun. The current model has these things.
Is all atomic nuclei positive?
Yes, though the overall charge of the entire atom is neutral due to the electrons orbiting it. If the atom becomes an ion by the removal or addition of electrons, its overall charge changes. But yes, the nucleus is made up of protons and neutrons. Protons are positive, neutrons are neutral.
