Particle Physics

4 of these dimensions are the regular ones most of us are familiar with; 3 of these are spatial dimensions: up-down, left-right and forwards-backwards. The fourth one is a time dimension.

In a 4 dimensional space you thus require four numbers to uniquely specify a certain location in space and time. A quick example would be the location of a meeting somewhere on Earth; you'd need four bits of information: the latitude and longitude of the location, the height and finally the time of the meeting.

In M-theory physicists assume there are 7 additional spatial dimensions. Thus in M-theory you would need a grand total of 11 numbers to uniquely specify a location in spacetime.

These additional 7 dimension are not equal to the regular 3 spatial dimensions in one important aspect; they are curled into small loops. This makes them periodic (if you walk in their direction you will after a while end up where you started), and they are very tiny. You can imagine them as small loops of additional space at every location in our regular 4 dimensional spacetime.

These loops cannot be seen however because they are so very tiny. If M-theory is correct we might be travelling in these dimensions all the time, but we don't notice it because they are so small.

A good analogy Briane Greene used is that of an ant on a garden hose. For the ant the garden hose seems 2 dimensional (3 if you count time); the ant can move forward and backwards on the hose, but it can also move around along the hose in a circular fashion. But if you stand some distance away the hose appears to be a line, a 1-dimensional object. You do not see the second curled-up dimension because it is too small because you are too far away.

In this way the extra dimensions M-theory requires are also hidden, but they might be spotted in modern particle collider experiments such as the LHC, since these can be used to probe the small distance scales where these additional dimensions might become important.

Sulfur-33 has 16 electrons since it is a neutral atom and the number of electrons is equal to the number of protons in the nucleus for a neutral atom.

Yes, the shape of an orbital represents the probability of finding an electron in a specific region around the nucleus. Different types of orbitals (s, p, d, f) have distinct shapes that determine the spatial distribution of electrons in an atom. This affects various properties such as chemical reactivity and bonding behavior.

Since Te 2- has a negative charge, there are more electrons. Two more in fact. This means Te (with a atomic number of 52, equaling the number of electrons) with two more electrons would be a total of 54 electrons.

Te 2- has 54 electrons.

The symbol for tin when it loses 2 electrons is Sn2+ - this represents tin in its 2+ oxidation state where it has lost 2 electrons.

The photon family consists of one member, which is the photon itself. Photons are elementary particles that carry the electromagnetic force and have zero rest mass.

No, photos are not made of subatomic particles. Photos are composed of photons, which are massless particles that carry electromagnetic force. Subatomic particles refer to particles like electrons, protons, and neutrons, which make up atoms.

all the electrons moving in their orbits have their natural frequency at which hey vibrate. in meta-stable state, when a photon of energy (equal to difference of energies b/w meta-stable and ground state) , electron starts to vibrate at their natural frequency. as a result its amplitude increases, and it moves to ground sate.

Protons and neutrons are in atomic nuclei, while electrons are located outside atomic nuclei in various probabilities of energetically favored states. Quarks are the fundamental particles that compose the hadron family of particles, of which protons and neutrons are members. Thus, you better believe quarks are found in atomic nuclei! In fact, because of the way the strong nuclear force acts on quarks, they can never be found on their own they are not found on their own at low energies but it is possible that they can become free at extremely high energies, as is the case in the hypothetical quark-gluon plasma. As we can observe them, however, they're always in protons and neutrons (or the various other hadrons).

The element with this electron configuration is calcium (Ca), which has 20 electrons.

No its not, energy can a be a rather vague term, but basically its the amount of work done. The formula for energy is given by Energy = Force x Displacement but there are many other types of energy but generally the flow of protons is not energy however the flow of electrons is. (Electrical Energy) Hope this helps =D

Just plug it into the Current formula. An ampere is one coulomb / second and the formula is I = q / t. Otherwise q / t = 1 amp ; let t = 1 sec q = 1 C ; The charge of an electron is 1.6 x 10^-19 C but is follows that there are 6.25 x 10^18 electrons in one second (inverse of charge). Remember that the amount of electrons in an ampere is dependent on time!

Protons and neutrons are made up of smaller particles called quarks. Protons are composed of two up quarks and one down quark, while neutrons are composed of one up quark and two down quarks. Quarks are bound together by the strong nuclear force.

A type of bond in which one atom gains electrons and one atom loses electrons is an ionic bond.

e<- ?

This type of electricity is called "static" because the electrons are not flowing through a circuit, as they would in an alternating current or direct current system, like the ones that power the lights in your home and your Xbox 360. Instead, they've accumulated in one place. If they get the chance, these negatively charged particles will transfer someplace else, in attempt to achieve a neutral balance. With lightning and the shock you receive from touching someone's sweater, this process happens very suddenly.

The history of swearing is complex and spans various cultures and time periods. It is difficult to attribute the invention of swearing to a single individual, as the use of profanity and vulgar language has likely evolved over centuries through cultural influences and societal norms.

Gravity is the fundamental force that is the result of warped spacetime, as described by Einstein's general theory of relativity. The presence of mass and energy warps the fabric of spacetime, causing objects to move in curved paths due to the force of gravity.

The human mind does not contain a specific number of electrons as it is not a physical structure that can be quantified in terms of electron count. The mind is a complex network of neurons and synapses that facilitate neural communication, rather than a physical entity that contains a specific number of electrons.

A structural formula representing 4 electrons shared between two atoms would involve a double bond, where two pairs of electrons are shared. This can be represented as an equal sign (=) between the two atoms in the chemical structure.

Phosphorus, which is the 15th element, has the most unpaired electrons among the first 20 elements. It has three unpaired electrons in its outer shell.

Electrons are the subatomic particles responsible for moving electrical current in a conductor. The flow of electrons from one atom to another creates an electric current.

emission of gamma rays to determine the elemental composition. This technique is commonly used for analyzing trace elements in various materials, such as archaeological artifacts, environmental samples, and industrial materials.

According to the Pauli exclusion principle, no two electrons in an atom can have the same set of four quantum numbers. Since electrons are fermions with half-integer spins, the two possible spin states for each electron (up or down) ensure that no two electrons in the same orbital have identical quantum properties. This helps stabilize the atom by minimizing electron-electron repulsion.

In this reaction we see an isotope of phosphorus,28P, undergo beta plus decay. In beta plus decay, a proton in the nucleus of an atom undergoes a transformation wherein an up quark becomes a down quark. This event, mediated by the weak nuclear force (or weak interaction), results in the proton becoming a neutron. When this happens, the atom changes from one element to another element in a process called transmutation. Here we see phosphorus become silicon, and the equation might look like this: 1528P => 1428Si + e+ + ve In this beta plus decay event, we see the phosphorus-28 atom transforming into a silicon-28 atom, and we see the positron (e+) and the neutrino (ve) kicked out of the nucleus on the back side of the event. Some links are provided below for extra investigation.

The Higgs field is a hypothetical field which explains mass. It is believed to be interaction with this field which gives particles mass. The photon is a massless particle, so it must not interact with the Higgs field.
