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.

What is the value of an atom in the periodic table?
However, the value given in the periodic table is an average of the mass of all isotopes of a given element. While the number of electrons does not contribute significant mass to an atom, isotopes have differing numbers of neutrons, which do affect mass.
Why do periodic tables not have periods?
Most periodic tables do not number them because they are fairly obvious, but some tables do. The period indicates the highest energy level att ained by electrons of an atom of the element in the ground state. How to Identify It: Period numbers are located on the left-hand side of the table. These are simple integer numbers.
What is the atomic number of an element?
Element Atomic Number. One number you will find on all periodic tables is the atomic number for each element. This is the number of protons in the element, which defines its identity. How to Identify It: There isn't a standard layout for an element cell, so you need to identify the location of each important number for the specific table.
Why do periodic tables omit electron configuration?
Most tables omit this value because it takes up a lot of room.
How to identify an element group?
How to Identify It: The number for the element group is cited above the top element of each column. The element group values are integers running from 1 to 18.
Where are period numbers located in a table?
How to Identify It: Period numbers are located on the left-hand side of the table. These are simple integer numbers. Examples: The row starting with hydrogen is 1. The row starting with lithium is 2.
What is the lowest atomic number?
The atomic number is easy because it is an integer that increases as you move from left to right across the table. The lowest atomic number is 1 ( hydrogen ), while the highest atomic number is 118. Examples: The atomic number of the first element, hydrogen, is 1. The atomic number of copper is 29.
How many periods are there in the periodic table?
Elements within a period display periodic table trends, moving from left to right, involving atomic and ionic radius, electronegativity, There are seven element periods.

Element atomic number increases as you move down a group from top to bottom or across a period from left to right. An element group is a vertical column on the periodic table. Atoms in a group share the same number of valence electrons. An element period is a horizontal row on the periodic table. Atoms in a period have the same number ...
How many valence electrons are in group 17?
For example, elements in group 1 have 1 valence electron, elements in groups 3-12 have a variable number of valence electrons, and elements in group 17 have 7 valence electrons. The lanthanides and actinides, located below the main table, all fit within group 3.
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.
What are the recurring properties of the periodic table?
These properties and their trends are: Ionization Energy - energy needed to remove an electron from a gaseous atom or ion. Ionization energy increases moving left to right and decreases moving down an element group (column).
What is the periodic law?
This led to the formulation of the periodic law, which states that the chemical properties of the elements are dependent on their atomic numbers.
