Are atoms just waves?
Atoms do in fact have a sort of wave behavior you might say.
Everything with mass does, even you.
For example, when we go to look for an atom by shining light of a small wavelength on it, we can only say with a certain probability of where we think it’s likely to be..
Who invented electron?
Joseph John ThomsonJoseph John Thomson (J. J. Thomson, 1856-1940; see photo at American Institute of Physics) is widely recognized as the discoverer of the electron. Thomson was the Cavendish professor of Experimental Physics at Cambridge University and director of its Cavendish Laboratory from 1884 until 1919.
What factors can make atoms unstable?
When the atoms of an element have extra neutrons or protons it creates extra energy in the nucleus and causes the atom to become unbalanced or unstable. Whether radioactive elements can become stable and if so, how. The unstable nucleus of radioactive atoms emit radiation.
How do atoms move?
In a solid, atoms are packed tightly together and move very slowly. In fact, they do not flow at all: they simply vibrate back and forth. … In a gas, the atoms move around very quickly and flow easily. As they move, they move away from each other to fill any container they are placed in.
What keeps matter together?
Gravity is the force that all objects with mass exert upon one another, pulling the objects closer together. … The tiny particles that make up matter, such as atoms and subatomic particles, also exert forces on one another.
Why do atoms behave as they do?
Elements are made of atoms, and the structure of the atom determines how it will behave when interacting with other chemicals. The key in determining how an atom will behave in different environments lies in the arrangement of electrons within the atom.
What determines the behavior of an atom?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom. … The number of protons in the nucleus determines the number of electrons in the atom. More on Atoms. Most atoms in the world around us are electrically neutral.
How do atoms behave in a liquid?
Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.
How do unstable atoms behave?
In some atoms the binding energy is not strong enough to hold the nucleus together, and the nuclei of these atoms are said to be unstable. Unstable atoms will lose neutrons and protons as they attempt to become stable.
How do you know if an atom is unstable?
An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.
Why is C 14 unstable?
Because carbon-14 has six protons, it is still carbon, but the two extra neutrons make the nucleus unstable. In order to reach a more stable state, carbon-14 releases a negatively charged particle from its nucleus that turns one of the neutrons into a proton.
How do atoms behave in gas?
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
