The Group 7 elements – fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At) – have seven electrons in the outer shell.
the vertical columns are called groups. elements in the same group are similar to each other. the metals are on the left and the non-metals are on the right. the main groups are numbered from 1...

There are total 18 different groups in Periodic table. 1. Group 1: Alkali metals group(hydrogen not included) 2. Group 2: Alkaline earth metals group 3. Group 3-12: Transition and Inner transition metals group 4. Group 13: Boron group 5. Group 14: Carbon group 6. Group 15: Nitrogen group 7. Group 16: Oxygen group 8. Group 17: Halogen group 9.

Groups are the vertical columns on the periodic table. There are total 18 vertical columns on periodic table. Hence there are 18 groups. The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons. For example; Example of group 1 All the elements of group 1 are highly reactive to water....

Give the name and location of specific groups on the periodic table, including alkali metals, alkaline earth metals, noble gases, halogens, and transition metals. Explain the relationship between the chemical behavior of families in the periodic table and their electron configurations.
Dec 6, 2019 · Group 2 elements are called alkaline metals because they form alkaline solutions, hydroxides, when reacting with water and their oxides are found in the earth’s crust. ALKALINE METALS. They have low electron affinity. Group 1 metals are less reactive than group 2 metals. Its valence shell contains 2 electrons; They have low electronegativity
Sep 18, 2024 · The metals whose oxides make up the alkaline earths then came to be known as the alkaline-earth metals and have been classified in Group 2 (IIa) of the periodic table ever since Russian chemist Dmitry Mendeleyev proposed his first table in 1869.
