Mar 29, 2019 · Categorize ionic bonds. Ionic bonds usually form between metals and non metals. When each atom ionizes to an anion or cation, there is a strong dipole. Ionic bonds have atoms with an electronegativity difference greater than two. Bonds between calcium and chlorine are ionic. In 1909 Ernest Rutherford presented his model of the atom based on the famous gold foil experiment. Rutherford shot a beam of positively charged particles at a thin sheet of gold foil and, based on the plum pudding model, expected the particles to pass through the foil because the positive charge of the nucleus was thought to be evenly spread out.

Electrical resistivity (also called specific electrical resistance or volume resistivity) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current.

The bond is therefore stronger, H+ is harder to remove, and K2 is lower. b) two points. Polar H2O can separate ionic NaOH into Na+ (aq) and OH?(aq) giving a basic solution. In HOCl, chlorine has a high attraction for electrons due to its greater charge density. This draws electrons in the H-O bond towards it and weakens the bond.
This is known as rainbow scattering, and it is also observed in scattering events such as atomic/molecular collisions or ion collisions with ordered surfaces. 5references Most introductory textbooks mention rainbows and the angles at which they can be observed, but do not necessarily explain why rainbows are bright.

collision model: The theory that chemical reactions are the result of collisions between molecules that are strong enough to break bonds in the reactants, resulting in a rearrangement of atoms to form a product or products.

In case of NaCl it is calculated as Molar mass of NaCl = molar mass of Na+ + molar mass of Cl– = (23 g mol–1) + (35.5 g mol–1) = 58.5 g mol–1 Let us take some more examples of ionic compounds and calculate their molar masses.

The greater the frequency of successful collisions between reactant particles, the greater the reaction rate. Temperature, concentration, pressure and the use of catalysts affect reaction rate.
