A covalent bond is one in which the electron is (more or less) equally shared between atoms. An Ionic bond is where one atom has a greater attraction for the electron than the other. Ionic bonds are formed between those elements that are at opposite end of the Periodic Table: the further away from each other the two elements are the more ionic will be their bond, the closer together the more covalent will be their bond. The most covalent bonds are between atoms of the same element O2 Cl2 N2 ..... The most Ionic of bond are between the alkali metals (H, Li, Na, K, Rb, Cs, Fr) and the Halogens (F, Cl, Br, I, At). Of these Ionic character is also affected by the top and bottom extremes of the table so the most ionic bond possible would be FrF, although Francium is extremely extremely rare so the most ionic compound known is Cesium Fluoride.
Ionic bond is formed when one atom gives up electrons to another atom, resulting in the transfer of electrons from one atom to another. This transfer creates electrostatic attraction between the positively charged cation and negatively charged anion, forming a strong bond.
It is not necessary. The type of bonding you mentioned is called ionic bonding in which one atom looses electrons and other atom of any other element gains it.
But another type of chemical bond is also formed called as Covalent bond in which atoms of same or different element share electrons. For example:- Cl2, CH4 etc. are formed by covalent bonding
When an atom donates/receives an electron to form a compound, the particles of that compound have ionic bonding. This occurs between metals and non-metals.
The other bonding, covalent, occurs when atoms shareelectrons and bonds non-metals with non-metals.
ionic bond
Ionic bonds are formed due to the electrostatic attraction between oppositely charged ions. In this type of bond, electrons are transferred from one atom to another, creating positively and negatively charged ions that are held together by their opposite charges. Covalent bonds are formed when atoms share electrons in order to achieve a stable electron configuration. The force of attraction in a covalent bond arises from the shared pair of electrons being attracted to the positively charged nuclei of both atoms involved.
The reaction of hydrochloric acid with potassium hydroxide is a chemical change because new substances (salt and water) are formed that have different chemical properties than the original reactants. The release of heat is an indicator of a chemical reaction taking place.
The production of chlorine gas when calcium chloride is heated to decomposition is a chemical change. This is because a new substance (chlorine gas) with different chemical properties is formed as a result of a chemical reaction taking place between the calcium chloride and heat.
The molecules on the right side of an equation are called the products. These are the substances that are formed as a result of a chemical reaction taking place.
When a base reacts with an acid, the gas formed is usually carbon dioxide (CO2) or hydrogen gas (H2), depending on the specific chemical reaction taking place.
Giving is to taking is as living is to existing!
ions are formed based upon the valence electrons of the element and if the element is a metal or a nonmetal. S has 6 valence electrons and needs 2 more to be stable. it is a nonmetal. therefore, taking on 2 electrons gives S a -2 charge
the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron

Taking is the opposite of giving
are the substances formed by a chemical reaction. In the burning of natural gas, carbon dioxide (CO2) and water (H2O) are the products formed by the reaction. Reactants and products can be elements or compounds, depending on the reaction taking place.
During a chemical change the structure of molecules (as chemical composition) is changed. Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
When you say that there is moisture in the air it pretty much means water in the air.It is a physical change, as no new products have been formed.
There would be no volcanoes and no crystals or diamonds and gold because they are formed because of the chemical reactions taking place inside the earth and because of the heat.
an insoluble sold formed in a chemical reaction that is taking place on a solution. Observed when the amount (concentration) of that substance is greater than its solubility. small crystals settel out in the container.
A chemical change is taking place.
