What is the first element on the periodic table? What is the centre of an atom called? True or false? Acids have a pH level below 7.
What is the main gas found in the air we breathe? An electron carries a positive charge.
Inorganic chemistry Inorganic chemistry studies materials such as metals and gases that do not have carbon as part of their makeup. Biochemistry Biochemistry is the study of chemical processes that occur within living organisms. Periodic Table s, p, d, f, g block Elements General Configuration of elements s-block elements included the elements of group 1 and group 2 of the periodic table. So they are called as s — block elements. Most s-block elements are highly reactive metals due to the ease with which their outer s-orbital electrons interact to form compounds The metals Lithium Li , sodium Na , potassium K , rubidium Rb , caesium Cs and francium Fr which have one electron in their outermost shell belongs to group I.
They are called as alkali metals as they react with water to form hydroxides which are strong bases or alkalies.
Hydrogen is highly chemically reactive, like the other s-block elements, but helium is a virtually unreactive noble gas. Of the p-block metals, several have fascinating properties. Gallium, in the 3rd row of column 13, is a metal that can melt in the palm of a hand. Tin, in the fourth row of column 14, is an abundant, flexible, and extremely useful metal. These elements are also known as the transition metals because they show a transitivity in their properties. The d-block elements are all metals which exhibit two or more ways of forming chemical bonds.
The d-orbitals can contain up to five pairs of electrons. These elements are not generally considered as part of any group.
They are often called inner transition metals because they provide a transition between the s-block and d-block in the 6th and 7th row. Chemistry exists whether we define it or not. And because an understanding of chemistry is so vital in so many other scientific fields, there are several different branches of chemistry that exist. In fact, chemistry is often studied so that scientists can better understand their own field.
There are five main branches of chemistry, each of which has many areas of study. Do you want to look into the topics such as organic chemistry, atoms, reactions, acids, and bases?
