The d-block elements consist of the elements in the middle three columns of the periodic table. These elements are the transition metals. The d-block elements are characterized by having their outermost valence electrons in a d-orbital. The d-block elements are generally hard, have higher melting points, and are more resistant to chemical reactions. Examples of …
P block elements are the elements found in the p-block of the periodic table. They are also known as the “other main group elements” because they are in groups 13-18 on the periodic table. They are characterized by having their outermost electrons in the p-orbital. P block elements are generally reactive and form compounds with …

P block elements are elements in the periodic table that have the highest number of electrons in their outermost shell, typically eight. These elements are located in columns 13 to 18 in the periodic table, and include elements such as boron (B), carbon (C), nitrogen (N), oxygen (O), fluorine (F), neon (Ne), sodium (Na), magnesium …
They all have a valence shell electronic configuration of ns2 np1-6. They all have relatively low ionization energies. They all have relatively high electron affinities. They all form covalent compounds due to their tendency to gain electrons. They all tend to form strong acids. They all have relatively low melting and boiling points.
The subshell electronic configuration is the arrangement of electrons in subshells (or orbitals) of an atom. It is usually expressed as a series of numbers denoting the number of electrons in each subshell (or orbital). The subshells (or orbitals) are grouped into four primary blocks: s, p, d, and f. The s block contains the …
The electronic configuration of chromium (Cr) is [Ar]3d54s1 and that of copper (Cu) is [Ar]3d104s1. Both chromium and copper have incomplete d-orbitals, but chromium has more electrons in its d-orbitals than copper. This is because chromium has two extra electrons in its d-orbital, while copper has one extra electron in its d-orbital. This peculiarity gives …
Noble gas electronic configuration refers to the complete electron configuration of the outermost shell of a noble gas, which is a group of elements in the periodic table that are highly stable due to having full valence shells. The noble gas electronic configuration for the first six noble gases is as follows: Helium (He): 1s2 …
When filling electrons in a subshell, electrons are filled in order of increasing energy, beginning with the lowest energy level. The subshells are filled in the order of 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
An energy crisis is a situation in which the demand for energy exceeds the supply. It can refer to shortages of oil and other fossil fuels, electricity, or other forms of energy. Energy crises can have a major impact on the economy and social well-being of a nation. Common causes of energy crises include conflict …
Green energy is energy that is generated from renewable sources, such as solar, wind, hydro, and geothermal power, as well as from more efficient use of natural resources, such as energy efficiency and conservation. Green energy does not contribute to climate change and is considered to be a clean and sustainable energy source.
