In the modern periodic table of elements, the following fall under group 15: Nitrogen (N) Phosphorus (P) Arsenic (As) Antimony (Sb) Bismuth (Bi)

Summary The periodic table is arranged in order of atomic number A period is a horizontal row of the periodic table. A group is a vertical row of the periodic table.

The modern periodic table is the current followed periodic table of classifying elements on the basis of their atomic number. It currently has 118 elements, with 28 of them being artificially made. It was created by Dmitri Mendeleev, and then organized better by Henry Moseley back around World...

Mendeleev made an early periodic table. In the modern periodic table, elements are in order of atomic number in periods and groups. Electronic configurations model how electrons are arranged in...

The modern or long form of the periodic table is based on the modern periodic law. The table is the arrangement of elements in increasing order of their atomic numbers. The modern periodic table is the present form of the periodic table. And it consists of 18 vertical columns and 7 horizontal rows.

The modern periodic table is developed after the periodic law and a periodic table given by Mendeleev. In the latter part of the 18th century, Mendeleev made his periodic table. Scientists did not know about the internal structure of the atom back then.

Seeing chemical elements arranged in the modern periodic table is as familiar as seeing a map of the world, but it was not always so obvious. The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.

The periodic table is one of the most valuable tools for chemists and other scientists because it orders the chemical elements in a useful way. Once you understand how the modern periodic table is organized, you'll be able to do much more than just look up element facts like their atomic numbers and symbols.
