When two atoms combine, the overlap of their atomic orbitals produces molecular orbitals.

Answer:

Explanation:

Molecular orbitals are mathematical functions that define the wave behavior of electrons within molecules, always from the point of view of quantum chemistry. Mathematical functions are used to find physicochemical properties, such as the probability of finding the electron in a given space.

So, according to the theory of molecular orbitals, the covalent bonds of the molecules are formed by overlapping atomic orbitals, so that the new molecular orbitals belong to the entire molecule and not to a single atom. During the formation of a bond, the atomic orbitals approach and begin to overlap, releasing energy as the electron of each atom is attracted by the positive charge of the nucleus of the other atom. The greater the overlap, the greater the release of energy and, therefore, the lower the energy of the molecular orbital. If the process of approximation of atoms continues, the atomic nuclei can repel each other, which causes the energy of the system to increase.

Molarity = moles / liter

a) M = 2/4 = 0.5 M

b) Moles = 4/(30 + 16 + 1)
= 0.085
M = 0.085 / 2 = 0.0425 M

c) Moles = 5.85 / (23 + 35.5)
= 0.1
M = 0.1 / 0.4
= 0.25 M

Why electronegative decrease going down the periodic table

liraira [26]

Moving down in a group, the electronegativity decreases due to an increase in the distance between the nucleus and the valence electron shell, thereby decreasing the attraction, making the atom have less of an attraction for electrons or protons.

PLEASE HELP!!! I need info regarding these guys and what they did to help with the discovery of atoms. Please ONLY ANSWER IF YOU

masya89 [10]

Democritus was the one who had theorized that atoms make up everything and they are indivisible.
Dalton was the creator of the first actual atomic theory, most of his research was on gasses and meteorology.
Thompson was the original man who put together the plum pudding model in which Rutherford later proved wrong during his career.
Rutherford had discovered the nucleus within an atom. He had put together gold foil experiment.
Bohr had developed the idea of neutrons and electrons surrounding the nucleus. He was also the creator of the planetary model we now use to calculate electrons with.
