WHAT IS AN IONIC BOND
kossel explained that inert gases r inert due to the electronic configuration which contains 8 electrons in their outermost shell
And other elements loss and gain electrons to form ions and to have electronic configuration same as Noble gas and to get stable

Answer:
A. Wipe down the glassware to remove any cleaning solvent.
Explanation:
· Remove stoppers and stopcocks when they are not in use. Otherwise, they may "freeze" in place. You can de-grease ground glass joints by wiping them with a lint-free towel soaked with ether or acetone. Wear gloves and avoid breathing the fumes. The deionized water rinse should form a smooth sheet when poured through clean glassware.
Answer:
A and C
Explanation:
The term formula unit is use to indicate Simple-Whole Ratios of ions in a compound. KEY WORD! RATIO!
solution:
Physical properties describe how a material looks. such as color, state of matter, shininess, Other physical properties include density, mp, bp, brittleness, malleability, conductivity, ductility, solubility in water. A physical property can be determined without changing the identity of the material.
Chemical properties describe how a material behaves.such as does it burn, does it corrode, does it react with air, does it react with water, does it act like a metal by giving away electrons o like a nonmetal by taking electrons, what type of bonds will it form, or is it inert, is it acidic or basic, Chemical properties can only be determined during a chemical reaction.
Explanation:
The given following standard cell notation.
Mg(s) | Mg^2+ (aq) || Aq^+(aq) | Aq(s)
Oxidation:
....(1)
Magnesium metal by loosing 2 electrons is getting converted into magnesium cation. Hence, getting oxidized
Reduction:
...(2)
Silver ion by gaining 1 electrons is getting converted into silver metal. Hence, getting reduced.
Overall redox reaction: (1)+2 × (2)
