Particle Physics

Relatively recent experimental results have confirmed what philosophers throughout history had theorized all along; that all matter is made up of elementary particles. Those curious about this cutting-edge field of physics known as particle physics should post their questions here, including those about fundamental particles, fundamental forces, Grand Unified Theories, and the extraordinary devices that have been or need to be engineered to research them.

What is the difference between electron and elektron?

User Avatar

Asked by Wiki User

Elektron is the spelling for the Greek word meaning "amber". It originated as the namesake for the negatively charged subatomic particle known as the electron because of amber's affinity for developing a static charge when rubbed against certain materials, such as wool. In fact, while wool develops a positive charge (meaning it loses electrons) amber develops a negative charge by rubbing electrons off the wool.

Do isotopes have the same number of protons and electrons?

User Avatar

Asked by Wiki User

YES!!!

The difinitive answer is ' Isotopes of an element have a DIFFERENT number of neutrons'.

Takinf an example. The element Hydrogen .

It has three isotopes. They are: -

#1 ; protium ; 1 proton , 0 neutrons, 1 electron ; Atomic mass '1'

#2 ; deuterium ; 1 proton , 1 neutron , 1 electron ; Atomic mass '2'

#3 ; tritium ; 1 proton 2 neutrons 1 electron. 'Atomic mass '3',

Carbon also has three isotopes biz.,

# 1 ; Carbon-12 ; 6 protons, 6 neutroins, 6 electrons ;Atomic mass '12'

#2 ; Carbon-13 ; 6 protons, 7 neutroins, 6 electrons ; Atomic mass ''13'

#3 ; Carbon-14 ; 6 protons, 8 neutroins, 6 electrons ; Atomic mass '14'.

Notice in each case the number of neutrons changes, the number of protons remains the same, otherwise it is a different element. The Atomic mass is the sum of the protons and neutrons.

NNB Every element has isotopes.

NNNN Do not confuse 'Isotopes' with 'Allotropes'. Allotropes are elements exhibiting a different physical form/appearance.

What occurs when an atom loses an electron?

User Avatar

Asked by Wiki User

It becomes an ion. Ions are atoms that have either lost or gained an electron. Since this on lost an electron, it got a positive 1 charge.

In an atom protons are always?

User Avatar

Asked by Wiki User

Protons are always in the nucleus of an atom.

The number of protons indicates the element, its position in the periodic table.

Protons a deemed to have a charge of (+)

Protons are deemed to have a relative mass of '1' .

The total number of protons and neutrons in the nucleus of an atom is the Atomic Mass. Collectively they are named as 'Nucleons'.

What does qcd mean?

Asked by Wiki User

In a business environment the acronym QCD stands for Quality, Cost and Delivery.

This is a very well respected system for measuring performance within a business area or department. The system first suggests the adoption of measures for the Effectiveness of the business area or activity, measured in terms of Quality performance and Delivery performance, each normally represented by a percentage result.

The cost element reflects the Efficiency measures relating to the activity. Each of these Cost elements relate to a different area of Resources that need to maintained in order to continue the business activity. Generally here we cover the ground relating to People, Materials, Workplace (overhead) and Equipment (plant, machinery etc). These areas of performance are normally measured in terms of the volume of output achieved per unit of resource (quantity or spend).

Each proton and neutron is made up of three quarks.

An atom that has more protons than electrons?

User Avatar

Asked by Wiki User

"Positively charged ions" or cation is the name given to an atom that has lost electrons, i.e. has more protons than electrons.

One gram of the salt is soluble in 2 ml of water, in 75 ml of ethyl alcohol, and in 50 ml of 90 % ethyl alcohol. The salt is insoluble in ethyl ether. Source is is a pdf from http://www.emeraldmaterials.com The complete link to the pdf file is found to the left of this answer under Web Links. It also includes the solubility in water a variety of temperatures.

What are good types of radiation?

Asked by Wiki User

Radiation is neither good nor bad. All types of radiation can be useful for some purpose, but many can be harmful in overdose conditions.

What is a Z-boson?

User Avatar

Asked by Wiki User

A Z-boson is a fundamental particle, a gauge boson, which, together with the W-boson, mediates the weak nuclear force, and has a charge of 0.

What is an antiquark?

An antiquark is an antiparticle of a quark.

Is a neutron Bigger than a quark?

User Avatar

Asked by Wiki User

Yes, neutrons are bigger than quarks; it takes three quarks to make a neutron, and the whole is larger than the components. Based on the current understanding of the force between the quarks, we also have an idea of how far apart they are within the neutron.

What is particle collision?

User Avatar

Asked by Wiki User

Particle collision usually refers to two subatomic particles slamming into each other at high speeds causing them to break into smaller particles. These speeds are created by particle accelerators.

What is weak interaction?

User Avatar

Asked by Wiki User

Weak interactions are interactions between subatomic particles that are mediated by the weak nuclear force. The first such interaction discovered was Beta Decay in radioactivity, where a neutron decayed into a proton, an electron, and a neutrino. The weak force is mediated by the W+, W-, and Z intermediate vector bosons being transferred between quarks.

How is a proton accelerated in a particle accelerator?

User Avatar

Asked by Kd77

Using electric fields. But velocity is increased step by step. In case of linear accelerator successive alternating right polarity accelerates to a higher uniform speed and it travels through proportionate lengthy tunnels. In case of cyclotron both electric (alternating) and intense magnetic field are used to increase the speed step by step.
