More neutrons than protons.
Fluorine needs one more electron to have a stable octet, as it has 7 valence electrons and stable octet configuration is achieved with 8 electrons.
Isotopes that are unstable are prone to nuclear decay. They decay because the nuclei of the atoms of that isotope are unstable. The instability within the nuclei creates possibilities for a breakdown in the nuclear arrangement with the emission of a particle or particles and/or energy. The particular arrangement of neutrons and protons in the nucleus, i.e., the relative numbers of these nucleons, will predispose some of the isotopes to undergo spontaneous nuclear transmutation. Put another way, the neutrons and protons in a given nucleus might not like being packed in their because there isn't a "happy correlation" between the number of protons and the number of neutrons. If we take a given isotope of a given element and add, say, a neutron, it becomes another isotope. Is this new isotope stable? Does it like the new arrangement or will it be unstable and prone to decay? What if we add another neutron? How about then? How about with another neutron? Get it? It's the same if we start fooling around with the number of protons. Some isotopes of a given element are stable and some are not. There may not be any stable isotopes of a given element, like with radon. Hope this helps.
Neutrons help stabilize the nucleus by balancing the repulsive forces between positively charged protons. The presence of neutrons adds an attractive nuclear force that overcomes the electrostatic repulsion between protons, contributing to the stability of the nucleus. Additionally, neutrons play a crucial role in preventing spontaneous decay of the nucleus by helping to balance the number of protons and neutrons in the nucleus.
It'll have to lose two to have a stable octet.
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
Fissioning unstable nuclei can release a significant amount of energy, which can be harnessed for power generation in nuclear reactors. This process also helps in reducing the size and mass of the nucleus, leading to a more stable configuration.
By the intermediate of a nuclear reaction this new element is obtained.Now heavy elements are bombarded with nuclei from other elements.
no it cant because multicellular organisms need specilized cells in order for them to remain stable to focus in one job
the banjo bike is not possible to make as soon as you turn a wheel it will not work and if it does work it will not remain stable
its not stable because last orbit need to loose electron to be stable
no. if the atom is stable it does not need to form any more compounds
It is recommend that web maintenance be done only when it is absolutely necessary. Otherwise clients may feel that the site is not available when they need it the most.
Nuclear decay is any spontaneous process where unstable nuclei release extra energy to arrive at a more stable state. Typical decay processes are Alpha, Beta, and Gamma. Some large unstable nuclei (e.g. Plutonium-240) can sometimes decay by spontaneous fission.Nuclear fission is a process where certain large nuclei (e.g. Uranium-235 & Plutonium-239) absorb a neutron and then split into two smaller nuclei and a few free neutrons. Some large unstable nuclei (e.g. Plutonium-240) don't need to be hit by a neutron to fission.Nuclear fusion is a process where small nuclei under unusual conditions of very high temperature and very high pressure combine to form larger nuclei.All three processes above are exothermic.In stars nuclear fusion stops at nickel and iron (further fusion past this would be endothermic). If all we had was the above processes then that would be where the periodic table ended (therefore there could not be nuclear fission as such heavy nuclei could not exist). However stars die, and some die so spectacularly we call them supernovas.When a supernova occurs, an intense shock wave blows all the outer layers of the star away at very high velocity. At these velocities nuclei collide so hard that normally impossible endothermic nuclear fusion reactions occur. The rest of the periodic table is filled here, including many transuranics not found naturally on earth (e.g. Americium, Californium, Berkelium).
To build a heavy bag stand, you will need to gather materials such as metal pipes, connectors, and a sturdy base. Follow a design plan or tutorial to assemble the stand, ensuring it is stable and can support the weight of the heavy bag. Consider adding extra support or weight to the base for added stability. Make sure to securely attach the heavy bag to the stand before use.
what education do I need to become a heavy duty mechanic
Yes. Alpha particles can be a product of radioactive decay, and alpha particles are simply Helium nuclei. Unless they interact with other atoms, they will tend to pick up stray electrons (they need two) and become stable 4He atoms.
