(resulting in different isotopes of the same element). electrons exist in energy levels or shells around the nucleus, and each shell can hold a specific number of electrons. example of an atom: atomic number: 6 (carbon) protons: 6 neutrons: 6 electrons: 6 (2 in the first shell, 4 in...

The single most important characteristic of an atom is its atomic number (usually denoted by the letter Z), which is defined as the number of units of positive charge (protons) in the nucleus. For example, if an atom has a Z of 6, it is carbon, while a Z of 92 corresponds to ...
The number of protons in an atom is unique to each element. For example,carbonatoms have six protons,hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical be...

atom, and this number determines or decides the nature of the element. Each oxygen atom has eight protons in its nucleus, while each aluminum has thirteen. We call these substances elements because all their atoms are of the same type;they all have the same number of protons in the nucleus...
