How can the periodic table identify the properties of chemical families?
Periodic table group elements with same properties together. Hence their properties can be identified.
Is it true or false that across a period from left to right the properties of elements change according to a pattern?
Yes, properties change according to pattern along a period. For example- atomic size decreases along a period. This is due to increasing nuclear charge.Yes, most of the properties change according to a pattern. Atomic radii, electronegativity changes according to a pattern. But properties like ionization energy does not change according to a pattern.
