Helium Atom and Alpha Particle comprise two protons and two neutrons. Helium is a stable element that can be encountered in nature. alpha particles are tiny positively charged particle that is released in certain forms that of decay radioactive.
Helium atoms are tiny, tiny structure that is found all over. It is composed of two neutrons, two protons and two electrons. This makes it stable and causing balloons made of helium to move.
Imagine a helium atom as a tiny fragment of the universe. Within this tiny atom, there are smaller items called neutrons, protons and electrons. Helium Atoms are distinct due to the fact that they have precisely two of each of them, two neutrons, two protons along with two electrons. They are extremely stable. You’ve likely seen them in balloons made of helium that floated because these molecules are lighter than air.
An alpha particle is smaller and more simple. It’s a mini-bullet that is composed of two neutrons and two protons without moving electrons. Alpha particles can be found in a variety of particular materials that have radioactivity. They could be dangerous to living creatures. Scientists employ them for crucial functions, specifically in gaining insight into small things.
What is Helium Atom?
Helium atoms are tiny particles that make all of the other particles that surrounds us. Imagine it as a small ball that has even smaller parts inside. The protons are the parts and neutrons, which are positive charges in the center.
They are also known as neutrons, which are neutral in charge and also located in the middle electrons, which are tiny positively charged specks that are buzzing all around the center. What makes helium atoms different is that they contain exactly the same number of protons as neutrons, which are two as well as two electrons.
This unique arrangement makes them very solid and is not arousing to join with other atoms to make things like air or water. Helium, the main gas in the world that causes balloons to increase in height, and this is due to the fact that the tiny helium atoms are much lighter than the atmosphere we breathe and so they lift the balloon to the sky.
What is Alpha particle?
Alpha particles are subatomic particle that is composed of two neutrons and two protons which gives it an electric charge. They are typically created through an alpha decay in unstable nuclei of the atomic. Despite their size, the alpha particles are quite heavy and possess very limited penetration capabilities, and can be quickly stopped by things like papers or even skin.
The fact that they are ionizing they can be harmful to living organisms, specifically when inhaled or consumed because they could damage tissues of the body. Positively they have numerous scientific applications, for instance in the field of alpha spectrometry, which allows for the identification of radioactive materials as well as in smoke detectors to detect smoke particles.
They also play a vital part in nuclear physics research which aid in understanding the atomic nuclei as well as fundamental

Properties and Behavior
Characteristics of Helium Atom
- Atomic number and mass: Helium’s atom has an atomic id of 2, meaning there are two protons inside its nucleus. The mass number of helium is typically 4 which is the total amount of neutrons and protons within its nucleus.
- protons and neutrons as well as Electrons: Helium atoms comprise of the protons as well as two neutrons as well as two electrons. The neutrons and protons are in the nucleus near the center, whereas the electrons travel around the nucleus.
- Electron configuration: Helium atoms have an electron configuration that is simple, having two electrons at the initial energy level. This arrangement of electrons makes helium extremely stable.
- Chemical Property: Helium is chemically inert that is, they cannot quickly make bonding chemically with other elements. This inertness can be attributed to its stable electron structure making helium a noble gases.

Helium Atom and Alpha Particle Origin and Formation
Helium atoms first appear through nuclear fusion processes in stars. The extreme heat and pressure causes hydrogen atoms in the universe to fusion to form Helium molecules. This process involves transformation to the hydrogen nuclei (protons) into the helium nuclei (two protons and two neutrons).
Helium atoms can also be produced through certain kinds of radioactive decay like alpha decay. On the other hand alpha particles are created due to alpha decay. It is a form of radioactive change that requires the release of two neutrons and two protons out of the nucleus in an unstable atom.
Alpha particles are also produced in nuclear reactions such as those occurring in nuclear reactors, or even during some particle-particle interactions.

How do helium atoms and alpha particles affect living Organisms?
Helium particles are generally healthy for living things because their chemical properties are inert, and they do not mix with different substances. Breathing in helium gas may be harmful as it may alter the oxygen levels in the lungs and cause oxygen depletion.
Contrary to that alpha particles, which emit in certain forms of radioactive decays, may cause harm to living organisms. When alpha emitting substances are inhaled or consumed or come in contact with living tissues, the intensity and charge of the alpha particles could create damage in cells as well as DNA and increase the risk of developing cancer and other health problems.
It is therefore essential to handle materials emitting alpha cautiously and limit exposure in areas in which living organisms are present.
