Name some exceptional element and their properties.
Answers
Answer:
The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.
Explanation:
Physical state: Metals are solid in state at room temperature but mercury is exception because it is liquid at room temperature.
Colour: Metals are mostly white or silvery grey but gold and copper are exceptions because gold is yellow in colour and copper is reddish-brown in colour.
Non-metals are colourless but gases like chlorine, bromine and iodine are exception.
Lustre: Non metals are not shiny but graphite and iodine are exception.
