determine the number of covalent bonds that are possible for atoms of the following elements: germanium, phosphorus, selenium, and chlorine. 2.24 On the basis of the hydrogen bond, explain the anomalous behavior of water when it freezes. That is, why is there volume expansion upon solidification...
The total distance within the outermost shell (in which electrons are present) and the total distance from the centre point of the nucleus of an atom are generally known as atomic radius. For example, the atomic radius of hydrogen (H) is equal to 12...
