Q:

Where are electrons located in the atom?

A:

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.

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.

  • Q:

    What are valence electrons?

    A:

    A valence electron is a type of electron present in an atom that works to aid in the process of chemical bond formation with other atoms. These electrons are present in the outer shell of an atom.

  • Q:

    What is the structure of an atom?

    A:

    An atom is comprised of a central portion called a nucleus that contains protons and neutrons. Electrons orbit the nucleus and are typically found in a one-to-one ratio with protons. Different stable atomic configurations are called elements. Hydrogen is unique in having one proton, one electron and no neutrons.

  • Q:

    How do you define "atomic radius?"

    A:

    The term "atomic radius" refers to the measured distance between the nucleus of an atom and the furthest orbiting electron. The outermost electron is referred to as a valance electron. The effective nuclear charge of an atom directly affects the size of the atom and the atomic radius.

  • Q:

    What is the difference between atomic number and mass number?

    A:

    The atomic number of an atom is the number of protons that resides in the nucleus, while the mass number is the number of protons and neutrons combined. The atomic number determines the type of element an atom, while the number of neutrons determines the isotope of the element. Many elements naturally occur in the form of several different isotopes.
