The remaining elements are metalloids, which share ...
Periodic Table of Elements
Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
The Parts of the Periodic Table
The transition elements or transition metals occupy the short columns in the center of the periodic table, between Group 2A and Group 3A. They are sometimes called the d-block elements, since in this region the d-orbitals are being filled in, and are also referred to as B-group elements since in most numbering systems of the columns on the periodic table the numerals of these groups are ...
Labeled Periodic Table | Science Trends
The Atomic Radius Trend refers to the fact that as you follow the periodic table down a group of elements, atomic radius tends to increase, which reflects the fact that as you move down a column another electron shell is added to the atom for every new row in the periodic table. Due to the fact that there is an increased number of electrons per ...

List of chemical elements
This is a list of the 118 chemical elements which have been identified as of 2021. A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei (i.e., the same atomic number, or Z).. A popular visualization of all 118 elements is the periodic table of the elements, a convenient tabular arrangement of the elements by ...

Group one is composed of metals that have a +1 charge, while all the metals in groups 2,3,4,5,6,7,8,9,10,11,12, and 16 have a charge +2. Then, metals in groups thirteen and fifteen have a charge of +3. Finally, all the metals in group 14 have a +4 charge.
A column of elements down the table is called a group.There are 18 groups in the standard periodic table. Each group has a number: from 1 to 18. Elements in a group have electrons arranged in similar ways, according to the number of valency electrons, which gives them similar chemical properties (they behave in similar ways). For example, group 18 is known as the noble gases because they are ...
