Cobalt electron configuration is [Ar]3d7.4s2.
Nitrogen electron configuration is [He]2s2.2p3.

Yes, but you have to take into account how clumsy the atom is for it to lose a neutron and how much of a kleptomaniac it is to steal one from another atom.

Hydrogen atoms have no neutrons because they are female and helium have two because they are male. Other elements have more neutrons because they are a freak of nature.

When atoms share electrons, the electrical attraction of an atom for the shared electrons is called the atom's electronegativity. Electronegativity is a measure of the ability of an atom to attract shared electrons towards itself in a chemical bond.

The final electron acceptor in glycolysis is oxygen, which is needed for the production of ATP in aerobic respiration. Oxygen captures the electrons at the end of the electron transport chain to form water.

Positrons don't last long because they are anti-electrons; they are antimatter. And they will combine with an electron after their appearance, and do so in a relatively short period of time. Both particles are oppositely charged and attract each other. And in an event called mutual annihilation, the total mass of both the positron and the electron are converted into energy.

This research involves using modern techniques to study the behavior of perturbative amplitudes in N4 supersymmetric theories. By re-evaluating the ultraviolet properties of multi-loop N8 supergravity using twistor theory, researchers aim to gain insight into the ultraviolet behavior of this theory and potentially uncover new insights or connections in supersymmetric theories. Overall, this approach may provide a deeper understanding of the underlying structure of these theories and contribute to ongoing developments in theoretical physics.

Atoms are composed of neutrons, protons, and electrons. Neutrons and protons make up the nucleus of the atom, while electrons orbit around the nucleus in specific energy levels or shells. The number of protons in the nucleus determines the element of the atom.

Acidic solutions contain very high concentrations of hydrogen ions. In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions.

proton, in nucleus

Elements with 5 protons are in Group 15 of the periodic table and include nitrogen.

No, protons and neutrons do not have the same mass. Protons have a slightly smaller mass than neutrons. The difference in mass between the two particles is due to the different composition of quarks that make up each particle.

This is essentially correct. The electrons and protons have equal but opposite charges, and the fundamental law of electrostatics is that opposite charges attract and like charges repel. The positive charge on the nucleus attracts and "holds" the electrons in orbit about the nucleus. It is electromagnetics that holds the electrons in orbit about that nucleus.

Answer2:

The attraction of the positive nucleus attracts the electrons to the nucleus by a centripetal force vp/r where v= Z alpha c. The electrons exeert a centrifugal force cDEL.P = -cp/r cos(P). When the orbit is stable the centripetal force equals the centrifugal force vp/r = cp/r cos(P) and the electrons do not fall into the nucleus.

The balance gives v/c = cos(P), the redshift. This is the result of the Quaternion Energy W = -vh/r + cP, the atom has a scalar energy -vh/r and a vector energy cmV=cP, the Momentum vector energy. The mystery of what holds the electron from falling into the nucleus is the Divergence of the vector energy. Physics has come to grips with the fact that energy is a Quaternion quantity with a vector energy and the Divergence of the vector energy creates the centrifugal force, the cosmological constant force and the Dark Energy.

Neutrons are stable subatomic particles and do not decay or change into other particles under normal conditions. However, electrons do not undergo nuclear decay but can change in energy levels within an atom.

Electrons can carry electrical charge and flow through conductors to create electric current. They also play a critical role in chemical bonding, allowing atoms to form molecules through sharing or transferring electrons. Additionally, electrons are involved in generating electromagnetic fields and radiation.

Electrons cannot be fused together. They are fundamental particles that carry a negative charge and repel each other due to their like charges. Fusion typically involves atomic nuclei combining to form a heavier nucleus, not electrons.

The difference is one between an cumulative signal vs a transient signal. Oxygen uptake reflects metabolic activity in the neurons. Areas of the brain that participate in a task will be preferentially marked by the tracer, but that signal will dissipate fairly quickly as the oxygen leaves the cell as carbon dioxide. The FDG-PET-CT is a cumulative signal as the active tissue will have an increased glucose transport into the neurons, but as the glucose is cleaved inside the neuron to supply metabolic needs the tracer part of the molecule stays inside the active neurons. So since most of the brain is active at some level this results in a background staining and a poor signal to noise ratio.

Protons and neutrons are both subatomic particles found in the nucleus of an atom. They have approximately the same mass, with protons having a positive charge and neutrons being electrically neutral.

The electron configuration for a 'p' orbital is represented as n + 1s2 + n + 2s2 + n + 2px1/py1/pz1. Here, n represents the principal quantum number, which determines the energy level of the orbitals in which the electrons are located.

When you say Ion you have to specify whether its negative or positive and the number associated with it. For example: if its Li 3- it means it has 3 more electrons then regular Lithium (which has 3 electrons) that makes it 6 electrons and 3 protons (this nr doesnt change) for Li 3-. Obviously calculations vary depending on the type of ion.

You would represent a pair of shared electrons (a covalent bond) with a single line between the symbols of the elements in a structural formula, or as two dots between the elements in a Lewis Dot diagram.

The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or atomic mass units.

Silicon-26 is a synthetic isotope of silicon; it is a man-made isotope. Additionally, silicon-26 is pretty unstable, and it has a half life of only about 2.234 seconds. This unstable isotope of silicon undergoes beta plus decay, which is also called positron emission. The result is the creation of an atom of aluminum. In the positron emission of silicon-26, let's start with the equation. Here it is: 1426Si => 1326Al + e+ Here we see Si-26 become Al-26. Inside the silicon-26 nucleus, the weak interaction (weak force) mediates the conversion of a proton into a neutron. When that happens, the silicon atom changes into an aluminum atom because there is one less proton in that used-to-be silicon nucleus. The atom's atomic number goes down by one, and the silicon becomes aluminum. This is an example of nuclear transmutation; it is the conversion of one element into another. We also see a positron (e+) leave the nucleus in the event, and this is why we sometimes call this type of beta decay positron emission. The positron that leaves this decay event has a great deal of kinetic energy, and it's really flying when it is ejected from the nucleus. The Al-26 that results is itself unstable, and the excited nucleus is a gamma emitter. Eventually though, the Al-26 "settles down" a bit. It has a really long half-life - some 7.17 x 105 years. It, too, will eventually decay, but it might undergo beta plus decay, or it could undergo electron capture. In either case, it becomes magnesium-26, which is stable.

An element's number of protons is the same as its atomic number. Thus, an atom with 21 protons has the atomic number 21. By looking up this element on the periodic table, one finds that it is scandium.
