Answer is: number of neutrons is different.
Isotopes are chemical elements with same atomic number, but different mass number (different number of neutrons).
For example, hydrogen (H), besides deuterium (mass number 2) and tritium (mass number 3), has isotope protium (mass number 1).
Atomic number is unique and defines an element. Isotopes of an element have same atomic number (same number of protons in nucleus).
Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.
Isotopes are variants of an element that have the same number of protons but different numbers of neutrons in their atomic nuclei. This difference in neutron count gives each isotope a unique mass number.
1. Mass Spectrometry: Mass spectrometry is a technique commonly used to identify and measure the abundance of isotopes in a sample. It works by ionizing atoms or molecules and then separating them based on their mass-to-charge ratio.
2. Nuclear Magnetic Resonance (NMR) Spectroscopy: NMR spectroscopy is another powerful tool for distinguishing isotopes. It exploits the magnetic properties of atomic nuclei to determine their local environment within a molecule.
3. Radioactive Decay: Some isotopes are radioactive, meaning they undergo spontaneous decay over time, transforming into other elements or isotopes.

The computer monitor powered by electricity that has been generated by a wind turbine involves several types of energy.
The types of energy involved are as follows:
1. Kinetic energy:The blades of the wind turbine rotate and move due to the force of the wind. This motion or movement of the blades is referred to as kinetic energy.
2. Mechanical energy:The kinetic energy of the wind is converted into mechanical energy as the blades of the wind turbine rotate. This mechanical energy is then transferred to a generator which converts it into electrical energy.
3. Electrical energy:The mechanical energy from the wind turbine is converted into electrical energy by the generator. This electrical energy is then transferred to the computer monitor via electrical wires.
4. Potential energy:As the wind turbines blades move, they gain potential energy. The potential energy is the energy that an object has due to its position or condition. The blades of the wind turbine gain potential energy as they move higher and higher due to the wind force. This potential energy is converted into kinetic energy as the blades rotate.
Thus, there are 4 types of energy involved in computer monitor powered by electricity that has been generated by a wind turbine.

There are 337.23 × 10²³ atoms in 4 moles of aluminum sulfite Al₂(SO₃)₃.
Explanation:
The questions ask how many atoms are in 4 moles of aluminum sulfite Al₂(SO₃)₃?
To answer this we use the Avogadro's number to devise the following reasoning:
if in 1 mole of Al₂(SO₃)₃ there are 14 × 6.022 × 10²³ atoms
then in 4 moles of Al₂(SO₃)₃ there are X atoms
X = (4 × 14 × 6.022 × 10²³) / 1 = 337.23 × 10²³ atoms
