In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
The periodic table and law are now a central and indispensable part of modern chemistry. The periodic table continues to evolve with the progress of science. In nature, only elements up to atomic number 94 exist; [a] to go further, it was necessary to synthesize new elements in the laboratory.
Bell heather, Erica cinerea, is the type species of the family. This is a list of genera in the plant family Ericaceae , which includes the heaths , heathers , epacrids , and blueberries . As currently circumscribed, the family contains about 4000 species into more than 120 genera classified into 9 subfamilies.

Cultivated highbush blueberries prefer sandy or loam soils, having shallow root systems that benefit from mulch and fertilizer. [5] The leaves of highbush blueberries can be either deciduous or evergreen, ovate to lanceolate, and 1–8 cm (1 ⁄ 2 – 3 + 1 ⁄ 4 in) long and 0.5–3.5 cm (1 ⁄ 4 – 1 + 3 ⁄ 8 in) broad.

A chemical element is a chemical substance whose atoms all have the same number of protons.The number of protons is called the atomic number of that element. For example, oxygen has an atomic number of 8, meaning each oxygen atom has 8 protons in its nucleus.
