Alkalies are a group of elements, typically including sodium and potassium, that typically have a pH greater than 7 (or are basic in nature). They are found naturally in soil, water, and plants. Alkalies are used in a variety of industrial and household applications, such as detergents, fertilizers, and cleaning products. Many metals are relatively …
Damage to trees, plants, and crops: Acid rain can reduce the growth and productivity of trees, plants, and crops. It can also decrease the fertility of soil, which can lead to lower crop yields. Pollution of lakes and rivers: Acid rain can increase the acidity of water in lakes and rivers, which can kill fish …
The basicity of acids is determined by the strength of their conjugate base. The stronger the conjugate base, the more acidic the acid. Acids with weak conjugate bases are considered weaker acids and have a lower basicity. Acids with strong conjugate bases are considered stronger acids and have a higher basicity. Examples of acids and …
Common components found in acids include hydrogen, oxygen, and carbon atoms. Hydrogen and oxygen are key components of many common acids, including hydrochloric acid (HCl), sulphuric acid (H2SO4), and nitric acid (HNO3). Carbon atoms are found in carboxylic acids, such as acetic acid (CH3COOH). Other common components found in acids can include nitrogen, chlorine, and …

Metalloids are elements that have properties that fall between those of metals and non-metals. Examples of metalloids include boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te).
Electro negativity is a measure of the ability of an atom or molecule to attract electrons when forming a chemical bond. It is measured on a scale from 0.7 to 4.0, with higher numbers indicating greater electro negativity. Fluorine is the most electronegative element, with a value of 4.0, while cesium has the lowest electro …
Ionisation energy is the energy required to remove an electron from an atom or molecule in the gaseous state. It is usually expressed in kilojoules per mole (kJ/mol). For example, the first ionisation energy of hydrogen is 1312 kJ/mol. This means that 1312 kJ of energy is required to remove 1 mole of electrons from …
Group 1: As the group number increases, the atomic radius of the element increases. Group 2: As the group number increases, the atomic radius of the element decreases. Group 3: As the group number increases, the atomic radius of the element increases. Group 4: As the group number increases, the atomic radius of the element …
Lanthanoids are otherwise known as rare earth elements, and are found in the f-block of the periodic table. They are comprised of the 15 elements from Lanthanum (atomic number 57) to Lutetium (atomic number 71). Commonly referred to as “inner transition metals,” lanthanoids are characterized by their shiny surfaces and low densities. Actinoids are also …

Transition elements are elements in the d-block of the periodic table that have partially filled d-orbitals. They are also known as transition metals. These elements are characterized by their ability to form multiple chemical bonds and coordination complexes. Examples of transition elements include iron, cobalt, nickel, copper, zinc, and chromium.
