The atoms are characterized as group. There are positively charged particles called protons, negatively charged particles are called valence electrons and the number of protons equals the number of electrons scattered in the common sphere.
Atomic is a powerful group. The positively charged particles called protons and negatively charged particles called electrons, protons, and electrons were scattered throughout the sphere.
Atomic features he group has particles with positive charge is called proton particles with negative charge is called the electron and proton number equal to the number of electrons scattered in a sphere.
