<span>d)S is not one of them.
Here's an easy way to remember them, attached: </span>
Explanation:
Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge.
Answer:
Chemical bond can be define as a force holding atoms firmly together to a form molecules.
Explanation:
Chemical bond is a strong attraction between atoms, molecules or ions that enhance the formation of chemical compounds. The bonds may be due from the electrostatic force of attraction between opposite charged ions or through the sharing of electrons.
Types of chemical bond
There are four types of chemical bonds
- covalent bond
- polar bond
- ionic bond
- hydrogen bond
Ionic bond involves the transfer of an electron which involves one atom receiving and the other giving out
Covalent bond involves the sharing of electrons between two atoms
Polar bonds involves two atoms connected by covalent bonds which may exert different attractions for the electrons in the bond resulting into unevenly charges distribution
Hydrogen bond: this is found mostly in water H2O. They are polarized
The original sample was a compound because it was composed of two different elements and was not purely one element
