Trends in the periodic table- Electronegativity Electronegativity is defined as the relative attraction of an atom for shared pairs of electrons in a covalent bond. An atom's electronegativity is affected by both its atomic number and the distance that its val... mia.rigby

2.5 The Periodic Table- Groups 2 and 7 2.5 The Periodic Table- Groups 2 and 7.-First Ionization Energy- Decreases down the group because as you move down the group the number of energy levels between the nucleus and the outer most electrons. This acts as a... Laura Perry
History of the periodic table 2 John Newlands was an English chemist who in 1865 classified the 56 elements that had been discovered at the time into eleven groups which were based on similar physical properties.Newlands noted that many pairs of sim... mia.rigby

Periodicity: Boiling Points Metal to Non-MetalMost striking trends across Periodic Table are: metals to non-metals solid to gas Na, Mg and Al are clearly metals, but Si is much harder to classify. Si has the shiny appearance of a metal, but is b... siobhan.quirk
Trends in the periodic table- Atomic radius The atomic radius can be defined as half the distance between the nuclei of 2 atoms of the same element that are joined together by a single covalent bond. eg the distance between 2 nuclei of hydrogen is 0.074 nm so t... mia.rigby

History of the periodic table 1 In ancient times, the Greeks believed that there were 4 elements, air, earth, fire and water. In turn, everything else was made up of a mixture of these 4 elements. This was the first notion of elements but didn't adv... mia.rigby
Groups in the Periodic table ALKALI METALS Alkali metals are group one metals found on the far left column of the periodic table. Includes Lithium, Sodium, Potassium, Rubidium and Caesium. Siba Al Dalaty
Introduction to the Periodic Table Robert Boyle first defined an element as a substance that could not be broken down into simpler materials by chemical means in the 1600's, and ever since then more and more has been learnt about the elements. The peri... mia.rigby
Trends in the periodic table- ionisation energy The ionisation energy is the minimum amount of energy required to remove the most loosely bound electron from an isolated atom of an element in its ground state, and is measured in kilojoules per mole. The second ioni... mia.rigby
The periodic table- Noble gases The noble gases make a group of chemical elements with similar properties: under standard conditions, they are all odourless, colourless, monatomic(atoms not bound to each other) gases with very low chemical reactivit... mia.rigby

Electronegativity Electronegativity Electronegativity - A measure of the tendency of an atom to attract a bonding pair of electrons. Electronegativity increases as you go across a period. It decreases as you go down a group. Electroneg... Leah Ratan
