an element whose properties are intermediate between those of metals and solid nonmetals

The periodic table is a tabular arrangement of the chemical elements

an element or substance that is not a metal.

a positively charged ion, i.e., one that would be attracted to the cathode in electrolysis.

any of the elements lithium, sodium, potassium, rubidium, cesium, and francium

a negatively charged ion, i.e., one that would be attracted to the anode in electrolysis.

each of two or more forms of the same element that contain equal numbers of protons

In each period, the atomic numbers increase from left to right.

the number of protons in the nucleus of an atom

are the vertical columns and are also referred to as groups.
