The ground state of a quantum-mechanical system is its stationary state of lowest energy; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state. In quantum field theory, the ground state is usually called the vacuum state or the vacuum. If more ...
For ionization of a diatomic molecule, the only nuclear coordinate is the bond length. The lower curve is the potential energy curve of the neutral molecule, and the upper curve is for the positive ion with a longer bond length. The blue arrow is vertical ionization, here from the ground state of the molecule to the v=2 level of the ion.
Ants as a colony also work as a collective "super mind". Ants can compare areas and solve complex problems by using information gained by each member of the colony to find the best nesting site or to find food. [2] Some social-parasitic species of ants, known as the slave-making ant, raid and steal larvae from neighboring colonies. [19]
Bonding in + can be described as a covalent one-electron bond, which has a formal bond order of one half. [3] The ground state energy of the ion is -0.597 Hartree. [4] The bond length in the ground state is 2.00 Bohr radius.
Fire ants sting and bite, particularly little kids since they can come into contact with dirt mounds playing outside. During those rare summer showers, fire ants will immediately turn up.
If no source of nucleation is introduced, water can cool down to −48 °C without freezing. [10] Therefore, when an insect maintains its body fluids in a supercooled state, there is the risk that spontaneous ice nucleation will occur. The temperature at which an insect spontaneously freezes is referred to as the supercooling point (SCP).
The ants clean each other's exoskeletons to decrease the presence of spores attached. [11] Also, ants can sense that a member of the colony is infected; healthy ants carry the O. unilateralis-infected individual far away from the colony to avoid exposure to spores. There are also reports that most worker ants remain inside the nest boundaries ...
The Saharan silver ant (Cataglyphis bombycina) is a species of insect that lives in the Sahara Desert.It is the fastest of the world’s 12,000 known ant species, clocking a velocity of 855 millimetres per second (over 1.9 miles per hour or 3.1 kilometres per hour).
