The volume of a gas is dependent on its temperature and pressure. At a constant pressure, the volume of a gas increases with increasing temperature and decreases with decreasing temperature.

Gases have no fixed shape or volume. Gases are highly compressible. Gases are made up of molecules that are in constant motion. Gases tend to diffuse and mix with other gases in their environment. Gases spread out evenly to fill the space they occupy. Gases exert pressure in all directions.

F-block elements, also known as inner transition elements, are the elements found in the f-block of the periodic table. They include the lanthanide and actinide series of elements. They have some common characteristics such as: They have relatively large atomic radii. They are highly reactive and tend to form multiple oxidation states. They display a …

Coloured compounds are compounds that are coloured due to the presence of certain ions, atoms, and molecules. The colour is a result of the absorption or reflection of light of certain wavelengths. Examples of coloured compounds include sodium chloride (NaCl), which is white; potassium permanganate (KMnO_4), which is purple; and copper sulfate (CuSO_4), which is …

The oxidation state of the d-block elements can vary from -2 to +8, depending on the element and the compound it is in. Most of the d-block elements have an oxidation state of +2, +3, +4, or +6 in their compounds.

The d block elements, also known as transition elements, are located in the middle of the periodic table, between groups 2 and 13. They are characterized by having partially filled d orbitals in their outermost shells. Most of the d block elements are metals, although there are some metalloids and nonmetals. They are generally harder, …

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.
