_______ found in the upper right corner of the periodic table. Most are gases at room temperature; few are solids.

These are usually found in the main body of the table. The highest occupied s sublevel and a nearby d sublevel contain electrons.

The________ is one-half of the distance between the nuclei of the two atoms of the same element when the atoms are joined.

Atomic number______________ within a group, the charge on the nucleus____________ and the number of occupies energy level increases.

The atomic radius within groups____________ as the atomic number increases

A(n) _______ is an ion with a positive charge

A(n) __________is an ion with a negative charge

The energy required to remove an electron from an atom

During reactions between metals and nonmetals, metal atoms tend to _______ electrons and non metals tend to _______ electrons. (think about their valance electrons)

The ability of an atom of an element to attract electrons when the atom is in a compound.

Who published a table of elements and was able to explain its usefulness showing properties in order of increasing atomic mass?
