Q:

Where are electrons located in the atom?

A:

Quick Answer

In most atoms, electrons occupy a zone exterior to the nucleus. Though electrons are often represented as particles in discreet orbits around the nucleus, they cannot be said to occupy a specific point in space. Rather, their position can be described as a wave function.

Full Answer

The exterior shell of the atom is not the only place electrons can be found in an atom. Though the electron shell is the only stable location for electrons, a heavy atom that undergoes beta decay can emit an electron from its nucleus. To avoid confusion, electrons emitted by the nucleus are referred to as beta particles.

    What are the main points of Rutherford's nuclear model of an atom?

    A:

    Rutherford's nuclear model of the atom is a planetary model with electrons orbiting around a compact nucleus of protons, and it serves as the basic model of the atom. His proposed electron orbitals were relatively simple, unlike the later complex ones. However, Rutherford was the first person to propose the existence of the neutron, based on the disparities between atomic mass and atomic number, explains an Indiana Northwest University website.

    What is a good analogy for nucleus?

    A:

    A nucleus of an atom can be compared to the sun of a solar system because the nucleus, like the sun, is the largest part of an atom and its electrons orbit around it, much like planets in a solar system. Atoms can also gain or lose electrons similarly to how stars can gain or lose planets.

    How is a coordinate covalent bond different from normal covalent bonds?

    A:

    Coordinate covalent bonds, also known as coordinate links or semipolar bonds, are different from normal covalent bonds because both of the electrons that are shared by the bonded atoms originally come from the same atom. This contrasts with normal covalent bonds, in which each atom gives up one of the two electrons that form the shared electron pair.

  • Q:

    Why do atoms get smaller across a period?

    A:

    Moving across periods on the periodic table from left to right, the atoms tend decrease in radius size because each atom has more protons than the atom before it, meaning there is more of an attractive force in the nucleus that pulls the electrons closer to the center. Even though there are both more protons and electrons, the attractive force of the protons wins out and makes the radius of the entire atom smaller.
