Physical properties of an element are those we can observe and feel with our senses. Also, the use special equipment can enhance our perception of these properties.
The same physical property can be shared different number elements.
On the periodic table, all the elements in group 1 and 2 are metals.
This is not very useful for scientists whose emphasis is to distinguish one atom from the other.
Therefore, physical properties are highly limited in the organization of the periodic table.
A carbon atom has 4 valence electrons in its outermost shell,thus it can form 4 covalent bonds.Two pairs of electrons are shared in a double bond between C-C atom.two more electrons are left which is shared with two hydrogen atoms.
Natural resources are naturally formed of course(wood copper fruits) and they are not distributed evenly due to competition of getting them and the prices of the resources
Applying law of electrostatic which states that like charges repel each other and unlike charges attract each other
N and S are unlike charges that turn and make the former repulsive force (due to two like charges N and N)to <em>reduce</em> and attractive force between N and S to <em>increa</em><em>se</em>
