Atomic radius and electrons because opposite charges attract, and more protons creates a stronger charge. The greater attraction draws the electrons closer to the protons, decreasing the size of the particle. Therefore, atomic radius decreases. Down the groups, atomic radius increases. This is because there are more energy levels and therefore a greater distance between protons and electrons. In addition, electron shielding causes attraction to decrease, so remaining electrons can go farther away from the positively charged nucleus. Therefore, size (atomic radius) increases. The following table summarizes the main phenomena that influence the atomic radius of an element: The electrons in the
Aonghas (given name) Aonghas (given name) Aonghas is a masculine given name in Scottish Gaelic. It is composed of Celtic elements meaning "one", and "choice". A variant spelling of the Scottish Gaelic name is "Aonghus". The Irish form of the Scottish Gaelic names is "Aengus". A pet form of the Scottish Gaelic name is "Angaidh", which is represented in English as "Angie", pronounced ""an-ghee"". The earliest form of the given name "Angus", and its cognates, occurs in Adomnán's "Vita Columbae" (English: ""Life of Columba"") as "Oinogusius", "Oinogussius".
