ionic bond or covalent bond between ca and br

In ionic bond the positive ion pulls the electron density of the anion towards itself and brings about polarisation of the anion. This causes the development of some covalent character in ionic bond..

. In the previous chapter one has observed the formation of a chemical bond by the transfer of electrons called the ionic bond. Atoms also acquire the stable noble gas configuration of having eight electrons in the outermost shell (called the octect rule) by mutual sha..

High ionisation energy Elements that have higher ionisation energies cannot form ionic bonds, as they cannot lose electrons easily. Instead, they acquire stability by mutual sharing of electrons, and therefore form covalent bonds..

Double covalent bond The bond formed between two atoms due to the sharing of two electron-pairs is called a double covalent bond or simply a double bond. It is denoted by two small horizontal lines (=) drawn between the two atoms, ..

Non-polar covalent bond When a covalent bond is formed between two atoms of the same element, the shared electron pair will lie exactly midway between the two atoms i.e. the electrons are equally shared by the atoms. The resulting molecule will be electrically..

Low ionisation energy Ionisation energy is the amount of energy, which is required to remove the most loosely bound electron(s) from an isolated gaseous atom to form a positive ion. In forming an ionic bond, one atom must form a cation by losing one or more electron..

Apart from coordinate covalent compounds, there are some compounds, which contain both ionic and covalent compound..

Mixed Bonding - Apart from coordinate covalent compounds, there are some compounds, which contain both ionic and covalent compounds. For example, sodium hydroxide In sodium hydroxide, there is an ionic bond between sodium ion Na + and hydr..

Covalent or metallic bonds, ionic bonds Chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2, N2, Cl2 Electrostatic attraction in salt crystals such as NaCl Inter-molecular forces in a solid and liquid Lewis dot structure..
