Particle Physics

Number of protons in the nucleus is the atomic number.

Protons and neutrons strongly attract each other when they are located close together within the nucleus of an atom due to the strong nuclear force. This force overcomes the repulsive electromagnetic force between protons, allowing them to stay together in the nucleus.

Protons determine what the element is.

Although the number of electrons and protons are the same(since the atom in electrically neutral), the number of electrons is more closely tied to the chemical properties than the number of protons, especially in reactions.

Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.

think of this protons/protine you need protine so its posotive neutron neuteral you know what that means and electrons electrick it hurts like hell if you touch it so negetive

The strong nuclear force is the force that keeps the nucleus of an atom together. This force is stronger than the electromagnetic force, which tends to repel positive protons from each other in the nucleus.

the hadron collider has a diameter of 3.8 metres and has a circumference of 17 miles (27 kilometres)

The String Theory was developed by multiple physicists in the late 20th century, including Gabriele Veneziano, Leonard Susskind, and Yoichiro Nambu. It aims to explain the fundamental particles and interactions of the universe in terms of vibrating strings.

since electrons are negative, you would subtract one from the original charge of the atom. For example, is the atom was neutral, the charge would then be 1-

A covalent bond is formed when two atoms share a pair of electrons to achieve a stable electron configuration. This sharing of electrons allows each atom to complete its valence shell and become more stable. Covalent bonds are typically found in molecules composed of nonmetals.

The main constituents to the atom are the protons (p+) and neutrons (n) of its nucleus, and their orbital electrons (e-). The p is notated with a positive charge, while the e- is negative -1.

No, the Large Hadron Collider is not going to end the world. It is a scientific experiment designed to study particles and forces in the universe. The safety of the collider has been extensively studied and there is no credible evidence to suggest it poses any danger to the world.

Molecules with nonpolar covalent bonds share electrons equally. This occurs when the two atoms have similar electronegativities. Examples include diatomic molecules like oxygen (O2) and nitrogen (N2).

It depends on what group or family the element is in. For example, Potassium is in the first group of family so it only has 1 valence electron. However, since nitrogen is in the 15 group of family, it does not have 15 valence electrons. For double digit families, you just take the second digit, and that is the number of valence electrons. Therefore, Nitrogen would have 5 valence electrons.

Electrons are lighter than proton

Electrons are elementary particles, and just happen to be among the lightest of them all. Protons and neutrons are not elementary (they consist of quarks and gluons) and just happen to be heavierer

One example of something that is not matter is electromagnetic radiation, such as light. While it can behave like particles in some situations, it does not have mass or occupy physical space in the same way matter does.

A meson is made of quarks - specifically a quark-antiquark pair. Some are called pions and kaons. They are all short lived particles that have been identified from high energy collisions. See Wikipedia for more detail.

From the observer's perspective, due to time dilation effects at high speeds, the pion would exist for approximately 0.000000041 seconds.

Well, the up and down Quark make Protons and Neutrons. Protons and Neutrons make atoms. Atoms make matter. Almost everything we see is made out of matter. If there where no quarks those things woudn't have been here.

The antiparticle of a quark is called as an anti quark.

Which has the same mass but other properties are opposite.

Example - Their charge.

From the family(group) of quark

Up has +2/3 whereas anti-up has -2/3.

Quark is a matter ( particle ) whereas an anti quark ( antiparticle ) is antimatter

A neutron has no charge, as it is electrically neutral.

Quarks are the smallest known fundamental particles that make up protons and neutrons, which in turn make up atomic nuclei. Quarks are never found in isolation, but always in groups of two or three to form the building blocks of matter.

James Chadwick discovered neutrons in 1932.

protons and electrons will always be = number
