If only at elements atomic number and weight are provided what other Atomic information can be determined for the neutral atom
If only the atomic number and weight are provided, the following atomic information can be determined for the neutral atom:
1. Number of protons: The atomic number of an element represents the number of protons in the nucleus of an atom. Therefore, the atomic number alone provides information about the number of protons in the atom.
2. Number of electrons: In a neutral atom, the number of electrons is equal to the number of protons. So, if the atomic number is known, it provides information about the number of electrons as well.
3. Number of neutrons: The atomic weight of an element represents the total number of protons and neutrons in the nucleus of an atom. Since the atomic number provides the number of protons, the difference between the atomic weight and atomic number gives the number of neutrons. Mathematically, Number of neutrons = Atomic weight - Atomic number.
4. Isotopic composition: The knowledge of atomic weight can give an indication of the isotopic composition of the element. Different isotopes of an element have different atomic weights. By comparing the atomic weight of an element to the known isotopes and their relative abundances, one can infer the isotopic composition of the neutral atom.
It's important to note that these determinations assume the atom is neutral and in its ground state, without any external influences such as electric charge or excitation.
