The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
because they have the same number of valence electrons
Elements in a group have same number of valence electrons and chemical properties. So, they have similar chemical reactions.
because day got dat swag
all all
families of elements with similar chemical properties are called groups.
Chemical properties of an element determine by the number of electron
As asked, the 92 "basic substances" that all matter is formed of are the chemical elements. As we move into advanced issues in science, we have to look a little beyond the chemical elements, but this is a foundational concept. Note that there are a few elements that are not "naturally occurring" on the earth, but can be synthesized.
Sulphur. If you google a chemical elements table it tells you that s = sulphur and then it tells you all the electrons and the chemical imbalance on it.
A chemical symbol for an element is one or two letters. These are found on the Periodic Table of elements. The chemical symbol is an abbreviation of the chemical element name.Example: O is the chemical symbol for Oxygen.K is the chemical symbol for Potassium.Pb is the symbol for lead.He is the symbol for helium.
the chemical and physical behavior of metallic elements
They can react with each other
the chemical and physical behavior of metallic elements
chemical behavior of a substance means how a substance behaves when it is reacted or kept isobaric with other substances or elements
chemical behavior of a substance means how a substance behaves when it is reacted or kept isobaric with other substances or elements
The chemical behavior of different elements is determined by valence electrons.
- allowed rational ordering of chemical elements- predicted the properties of unknown elements- the chemical behavior of chemical elements can be predicted- the atomic radius can be predicted- the melting point can be predictedand more
Number of electrons in the outer shell
their boiling point and melting point.....etc.
I would expect all elements in group 1 to have similar chemical behavior to that of sodium, except for hydrogen. Hydrogen is not a metal, but has only 1 valence electron like the other elements in group 1.
All chemical elements are formed from protons, neutrons (excepting H-1) and electrons.
