PHY 205 Lecture Notes - Lecture 40: Radium, Alpha Particle
Document Summary
Ionization energy required to remove an electron from a neutral atom in its gaseous phase. Atomic radius one-half the distance between the nuclei of two atoms. Melting point amount of energy required to break a bond to change the solid phase of a substance to a liquid. Consists of only one kind of atom, cannot be broken down into a simpler type of matter. Consists of atoms of two or more different elements bound together. Can be broken down into a simpler type of matter by chemical means. Has properties that are different from its component elements. Consists of two or more different elements and/or compounds physically intermingled, can be separated into its components by physical means and often retains many of the properties of its components. A homogeneous mixture of two or more components. Particles are larger than those found in solutions.
