A model of an atom shows eight electrons in rings that represent different energy levels. How many electrons are in each energy level? A. four in the first energy level, four in the second energy level. B. zero in the first energy level, eight in the second energy level C. two in the first energy level, six in the second energy level D. eight in the first energy level, zero in the second energy level

The correct option is;

C. Two in the first energy level, six in the second energy level

Explanation:

The electrons in an atom are arrange in orbital shells which are situated at different levels within the structure of the, depending on the energy of the electron. Electrons with the least amount of energy are found in the shell closest to the nucleus of the atom which is the first energy level

The maximum number of electrons that can be found in a given an energy level is obtained with the following formula;

The number of electron = 2 × n²

Where;

n = The number of the different energy level

Therefore;

The maximum number of electrons in the first energy where n = 1 is given as follows;

The number of electron = 2 × 1² = 2 electrons

The maximum number of electrons in the second energy level where n = 2 is given as follows;

The number of electron = 2 × 2² = 8 electrons

Given that there are only 8 electrons in the atom, we therefore have, 2 electrons in the first energy level and the remaining 8 - 2 = 6 electrons in the second energy level.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

first one is the correct answer
