3. A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well
4. s a tabular display of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry.
6. In physics and chemistry, ionization energy or ionization energy is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule
10. a region of an atom in which electrons of the same energy are likely to be found
11. are those in which the last electron enters the outermost s-orbital.
12. The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons

1. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.
2. Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements.
5. The noble gases make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.
7. symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond.
8. In chemistry, a group is a column of elements in the periodic table of the chemical elements.
9. defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.
