Answer:
Mendeléyev designed his table around the same time as a German chemist named Julius Lothar Meyer, who published it a year later. However, finally Mendeléyev's order was imposed. Do you know what his great success was? Help plis.
Mendeleev predicted the existence and properties of unknown elements that he called eka-aluminum, eka-boron, and eka-silicon, his table is based on atomic weight.
Explanation:
Gallium, scandium, and germanium were later discovered to coincide with his predictions. In addition to the fact that Mendeleev's table was published before Meyers, his work was more extensive, predicting the existence of other elements not known at the time.
El teorema de Pitágoras se generaliza a espacios de dimensiones superiores. Algunas de las generalizaciones están lejos de ser obvias. El teorema de Pitágoras sirve como base de la fórmula de distancia euclidiana.
Espero que esto ayude, que tengan un día bendecido y maravilloso, ¡así como uno seguro! :-)

Explanation:
The most reactive metals are found on the left of the periodic table, in the blue column, known as the alkali metals. Their reactivity increases as we go down column (group) one. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting.
