Class10 Metals and Non metals
Elements by periodic table can be divided up into metal, nonmetal, and metalloids
Elements by periodic table can be divided up into metal, nonmetal, and metalloids (in between) based on their properties. Everything from the left to the metalloid "stairstep" is a metal, and everything to the right is a nonmetal. The periodic table shows most elements are metals.
The structure and bonding of metals is also unique. A metallic substance has atoms that are closing packed to their neighboring atoms. There are two common arrangements for metals, one of which is the body-centered cubic. In this arrangement each atom is at the center of eight other atoms. The other arrangement is called the face-centered cubic, and this is the same as the body-centered cubic except the atom is the center of six other atoms. These arrangements cause a crystal structure.
As far as bonding goes, metals easily lose their outer shell electrons, or valence electrons. This property is what gives them their ability to easily conduct heat and electricity.
