What is the most stable structure?
Triangle is most stable structure.
If u apply force on any link or joint the net force is distributed all over the structure ie sides and joints.
This means all sides and joint experience force thus the force is distributed and this makes it more rigid and stable structure..
Why is a heavy nucleus unstable?
Solution : Heavy nuclie are unstable due to large repulsive forces between large number of protons in the nucleus.
What is Franciums half life?
about 22 minutesFrancium’s most stable isotope, francium-223, has a half-life of about 22 minutes. It decays into radium-223 through beta decay or into astatine-219 through alpha decay.
Is carbon a C or c2?
Diatomic carbon (systematically named dicarbon and 1λ2,2λ2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C2] or C2.
What is the most stable element in the universe?
IronWell, Iron has the most stable isotope(Iron-56), it has a large half-life which means it takes a fairly large amount of time to decay into the half of what was initially there.
Why is carbon so stable?
The bonding properties of carbon For one thing, carbon-carbon bonds are unusually strong, so carbon can form a stable, sturdy backbone for a large molecule. … Because a C atom can form covalent bonds to as many as four other atoms, it’s well suited to form the basic skeleton, or “backbone,” of a macromolecule.
Which is the most stable isomer?

What is the most unstable element?
franciumWhile it occurs naturally in uranium minerals, there is probably less than an ounce of francium at any time in the total crust of the earth. It has the highest equivalent weight of any element, and is the most unstable of the first 101 elements of the periodic system. Thirty-three isotopes of francium are recognized.
What is the rarest element?
AstatineAstatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time.
How do you know which ion is more stable?
The larger the atom, and the further the electrons from the nucleus, the more polarizable it is. The more polarizable the atom, the more stable the anion. Within a row of the periodic table, the more electronegative an atom, the more stable the anion.
Why are all elements above 82 unstable?
In the case of atoms of elements with a mass greater than 82, the level of binding energy does not allow stability. The force of repulsion between the particles that constitute the nucleus makes the atoms split and atoms of new elements are formed as they try to reach a nuclear configuration which is stable.
What is the most stable nuclide?
Nickel-62Nickel-62 is an isotope of nickel having 28 protons and 34 neutrons. It is a stable isotope, with the highest binding energy per nucleon of any known nuclide (8.7945 MeV).
What is a stable element?
Elements having the maximum number of electrons that can be accommodated in their last shell or orbit are known as stable elements. … Usually these elements do not take part in chemical reaction, because they are chemically stable elements. These elements are also known as noble gases and 18th group elements .
What makes an atom stable or unstable?
An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.
Is carbon stable or unstable?
Isotopes of Carbon Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time. The rare carbon-14 (14C) isotope contains eight neutrons in its nucleus. Unlike 12C and 13C, this isotope is unstable, or radioactive.
What is the least stable nucleus is?
The least stable nucleus is ‘highly radioactive nuclide’. Nuclear stability can be defined as a nucleus that it does not spontaneously emit any kind of radiation.
Why is C 14 unstable?
The nuclei of carbon-14 atoms are unstable because they have too many neutrons relative to protons, so they gradually decay.
Why is H+ unstable?
Hydrogen only has one electron in its lowest energy level. This is a very unstable arrangement, and hydrogen gas undergoes a variety of reactions so as to reach a stable electron configuration where its energy level is either empty of electrons, or filled with electrons.
Why even even nuclei are more stable?
Nuclides containing odd numbers of both protons and neutrons are the least stable and this means more radioactive. Nuclides containing even numbers of both protons and neutrons are most stable and this means less radioactive. than nuclides containing even numbers of protons and odd numbers of neutrons.
Why are some elements unstable?
Why some elements are radioactive (unstable). When the atoms of an element have extra neutrons or protons it creates extra energy in the nucleus and causes the atom to become unbalanced or unstable.
Why is iron the most stable nucleus?
The more stable a nucleus is, the more energy is required, per nucleon, to pull the nucleus apart. This stability is caused by the attractive nuclear force between nucleons. Iron 56 is the most stable nucleus. … This repulsion between distant protons leads to less binding energy per particle and instability.
