What is ionic bonding?
Transferring electrons, the atoms involved lose all gain electrons to form charged particles called ions
All the bounds strong in ionic bonding?
The ions formed are held next to each other by very strong forces of attraction between the oppositely charged ions. This electrostatic force of attraction ,which acts in all directions , is called ionic bonding
What is an ionic compound ?
A compound held together by strong forces of attraction between the oppositely charged ions called ionic bonding
What are isotopes ?
An isotope is where an atom are different. Isotopes are where they have the same element some protons , some electrons but different neutron
What is electronic configuration?
How many electrons are in each shell
What is one difference between the old and new periodic table?
An extra collum
What happens when an atom loses or gains electrons?
It becomes an ion
Which of metals and non-metals forms negative ions ?
Non- metals
What is distillation?
The evaporation and subsequent collection of a liquid by condensation as a means of purification
What is a mixture?
Combination of elements and compounds , not chemically bonded so can be separated
What is it called if solids dissolve in water ?
They would be soluble
Define an atom
The smallest particle of an element
What can atoms be joined by?
Bounds
What is the top number ?
Mass number
What is the bottom number ?
Atomic - proton and electron
What is the charge of protons , neutrons and electrons ?
N=0 , P=+1, E=-1
What can mixtures be separated by?
Filtration,crystallisation , chromatography, distillation , fractional distillation
What charge will it be if an atom gains ?
Negative , if it loses it will be positive
What is made if hydrochloric acid reacts with metal oxide ?
Chloride salts
What is made if you react sulphuric acid with metal oxide ?
Sulphurate salts
What is produced if nitric acid reacts with metal oxide ?
Nitrate salt
What are metal oxides ?
Compounds made from metal and oxygen
What are group 1 and group 7 ?
Alkali metals , halogens
What are lattices ?
Ionic compounds form these , they are strong and need a lot of energy to break they have high melting/boiling points
