Why is it known as the 'periodic' table?

Selecciona una de las siguientes respuestas posibles:

Because the properties of the elements show a periodic pattern.
Because it was arranged in six periods by Newlands.
Because it was arranged in six periods by Mendeleev.
Because it was the name coined by 20th-century chemists.

However, ' work was criticised by the Chemical Society in 1865, because:
- His groups contained elements that didn't have similar .
- He didn't leave any for to be discovered.
- He mixed up m and .

The ( positive, negative, neutral ) charge of the ( nucleus, protons, neutrons, electrons ) attracts ( electrons, ions, energy levels, other elements ) and holds them in place - the further away they are, the ( weaker, stronger, more variable ) the attraction. If there are lots of ( inner electrons, protons in the nucleus, neutrons in the nucleus, energy levels ), they get in the way of the ( nuclear, subatomic, negative ) charge, further reducing the attraction. This effect is known as '( shielding, blocking, interception, electron absorption, ion absorption )'.
