Why is Kobold called Kobold?
The name derives from the German Kobold for "evil spirits" or "goblins", who were superstitiously thought to cause trouble for miners because the mineral contained arsenic that injured their health and the metallic ores did not yield metals when treated with the normal methods.
Where did the name Cobalt come from?
The name derives from the German Kobold for "evil spirits" or "goblins", who were superstitiously thought to cause trouble for miners because the mineral contained arsenic that injured their health and the metallic ores did not yield metals when treated with the normal methods. Cobalt was discovered in 1735 by the Swedish chemist Georg Brandt.
Is cobalt a metal?
Cobalt is a brittle, hard metal, resembling iron and nickel in appearance. It has a metallic permeability of about two thirds that of iron. Cobalt tends to exist as a mixture of two allotropes over a wide temperature range. The transformation is sluggish and accounts in part for the wide variation in reported data on physical properties of cobalt.
What is the oxygen group on the periodic table?
Oxygen group is the group 16 on the periodic table.
How many groups are there in the periodic table?
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.

Who published the first periodic table?
Anne Marie Helmenstine, Ph.D. Updated March 04, 2019. Dmitri Mendeleev published the first periodic table in 1869. He showed that when the elements were ordered according to atomic weight, a pattern resulted where similar properties for elements recurred periodically.
Which side of the periodic table contains elements that are nonmetals?
Most elements are metals. They are found on the lefthand side of the table. The far right side contains the nonmetals, plus hydrogen displays nonmetal characteristics under ordinary conditions. Elements that have some properties of metals and some properties of nonmetals are called metalloids or semimetals.
What are the two sets of elements?
There are two sets of groups. The group A elements are the representative elements , which have s or p sublevels as their outer orbitals. The group B elements are the nonrepresentative elements, which have partly filled d sublevels (the transition elements) or partly filled f sublevels (the lanthanide series and the actinide series ). The Roman numeral and letter designations give the electron configuration for the valence electrons (e.g., the valence electron configuration of a group VA element will be s 2 p 3 with 5 valence electrons).
How are elements in the periodic table arranged?
Elements in the periodic table are arranged in periods (rows) and groups (columns). Each of the seven periods is filled sequentially by atomic number. Groups include elements having the same electron configuration in their outer shell, which results in group elements sharing similar chemical properties. The electrons in the outer shell are termed ...
What are the electrons in the outer shell of an element?
The electrons in the outer shell are termed valence electrons. Valence electrons determine the properties and chemical reactivity of the element and participate in chemical bonding. The Roman numerals found above each group specify the usual number of valence electrons. There are two sets of groups.
