Particle Physics

If you mean subatomic particle as in protons neutrons and electrons, electrons have the lowest mass.

If you are talking even smaller, leptons have extremely tiny rest masses.

Electron groups are pairs of electrons that exist around an atom, either in a single bond, double bond, triple bond, or lone pair. These electron groups determine the geometry of the molecule and play a significant role in determining its reactivity and properties.

Murray Gell-Mann and George Zweig independently introduced the concept of quarks in the 1960s as part of the quark model to explain the structure of protons and neutrons. Gell-Mann coined the term "quark," inspired by a line from James Joyce's "Finnegans Wake."

Down the group electron affinity decreases

Across a period electron affinity increases.

However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)

A neutron can transform into a proton, an electron, and an antineutrino through a process called beta decay. During beta decay, a neutron in the nucleus of an atom is converted into a proton, an electron (beta particle), and an antineutrino. This process helps maintain the balance of protons and neutrons in the nucleus.

Electrons that jump from object to object are typically involved in static electricity, where one object becomes charged by gaining or losing electrons. This transfer of electrons can occur through friction, conduction, or induction, resulting in the buildup of static charge on the objects involved. These charged objects can then attract or repel each other due to the imbalance of electrons.

The concept of atomic number had not yet been developed at the time of the first periodic tables, when atoms were still considered "indivisible units" and the concepts of protons, electrons, and neutrons were not yet known.

All the atomic nucleus (excepting the isotope 1H) contain a number of neutrons.

Quarks are the particles that make up protons and neutrons. There are no particles, as far as we know, that make up electrons.

The atomic number of carbon is 6 and it has six electrons. The mass number of it is 41 and therefore it has 8 neutrons.

chemical property

The energy in streams of moving electrons is known as electrical energy, which is a form of kinetic energy resulting from the movement of electrons through a conductor. This energy can be harnessed and used to power various devices and systems, such as electrical appliances, machines, and electronics.

Non-ionizing radiation, such as visible light and radio waves, are generally considered safe and have low energy levels that do not cause harm to humans. Ionizing radiation, such as X-rays and gamma rays, can be harmful in high doses and have enough energy to remove electrons from atoms, potentially causing damage to cells and DNA. It is important to limit exposure to ionizing radiation to protect against potential health risks.

Ionic compounds transfer electrons. In an ionic bond, one atom gives up electrons to another atom, resulting in the formation of positively charged cations and negatively charged anions that are then attracted to each other.

There are several ways in which elements can be separated by physical methods. Centrifuge If you grind an ore to sufficient fineness, you can use a centrifuge to separate an element based on its specific gravity. Panning is a more primitive version of this basic method. Gaseous Diffusion You can also heat an ore to the temperature at which a particular element becomes gaseous and separate it out.

Neutrons have no charge, because they are neutral. This means they have no charge at all, and their mass is also negligible, unlike Protons and Electrons.

A Proton has a positive charge - 'P' for 'positive' - and an Electron has a negative charge.

An easy way to remember these:

'N' for Neutral, 'P' for Positive. Since the only other atom is an Electron, it should be simple to remember.

The concept of baryons as a group of subatomic particles was developed by Murray Gell-Mann and Kazuhiko Nishijima in the 1950s. They observed and classified various particles based on their properties such as charge, strangeness, and isospin.

It is not letting me put the link in as normal, so I put the "dots" in.

Remember that momentum is conserved. Since initial momentum is zero (since it is at rest) the net momentum of the two particles must cancel each other to equal zero. They are traveling in opposite directions. Let the rest mass of one particle equal m1, then the rest mass of the other particle is (3.34 x 10^-27 kg) - (m1). Plug those into the relatavistic mass equations, and set the magnitudes of momentums equal. Then you can solve for m1.

In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).

total energy

E=gamma*m*c^2

where gamma = 1/sqrt(1-v^2/c^2)

K=E - mc^2 = (gamma-1)*(Rest Energy)

You know v, and can thus compute gamma, and you know the rest energy.

The force exerted only by protons nearest to each other is the electromagnetic force. This force is responsible for repelling or attracting protons based on their charges, with like charges repelling each other and opposite charges attracting each other.

A nucleus of vanadium contains protons and neutrons. Vanadium typically has 23 protons and 28 neutrons in its nucleus, resulting in an atomic mass of approximately 51.

bonds between atoms. These bonds determine the reactivity, stability, and physical properties of a substance. The most common types of chemical bonds are covalent and ionic bonds.
