List all possible unit formulas (chemical formulas) that can be constructed by the formation of binary ionic compounds from the following elements. (Separate substances in a list with a comma.) Cs (Z = 55), Ba (Z = 56), O (Z = 8), I (Z = 53), Sr (Z = 38)
Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.
List all possible unit formulas (chemical formulas) that can be constructed by the formation of binary ionic compounds from the following elements. (Separate substances in a list with a comma.)
- Binary ionic compound contains a metal and a nonmetal .Metals combine with nonmetals to give ionic compounds.
- Binary ionic compounds of Strontium Sr (Z=38) strontium has 2 valence electrons .Sr from cations Sr2+.Strontium reacts with iodine to form SrI2 And reacts with oxygen to form SrO strontium oxide.
- Cs,Ba,Sr has metallic elements and O,I are non metallic elements. Cs has one valence electron.
- Cs reacts with iodine to form Caesium iodide CsI
- Cs reacts with oxygen to form CsO2.
- Barium has 2 valence electrons.
- Barium Ba reacts with iodine to form BaI2 .Barium reacts with oxygen to form Barium oxide BaO.One ion of barium neutralizes one ion of oxygen,hence those two ions combine to form barium oxide.
