How many electrons does an atom have

Chemistry
1 answer:
inn [45]3 years ago
4 0
In this question, the most probable answer that you would get would be that it depends. It depends on what kind of element are we talking about here. What is important to remember about these is that the number of electrons must always be equal to the number of protons. To get the numbers of electrons and protons of a certain element, just locate the atomic number of the said element. The number of protons is equal to the atomic number and the number of electrons is equal to the number of protons which is equal to the atomic number. If neutrons were to be added in the picture, just take the atomic weight of the element then round it off to the nearest whole number to get its mass number. Subtract the number of protons to the mass number and the difference would be the number of neutrons.

A rigid container (volume cannot change) is filled with carbon dioxide gas at room temperature. The container is then placed in
Sedbober [7]

The reduction in the temperature leads to an automatic decrease in the pressure of the gas inside the he container. This is due to the decreased number of collisions per unit area of the container walls. Pressure law states that at constant volume, the pressure of a fixed mass of a gas is directly proportional to the absolute temperature.

Calculate the molar concentration of the Cl⁻ ions in 0.92 M MnCl2(aq).
scZoUnD [109]
MnCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MnCl2 that dissolves.
MnCl2(s) --> Mn+(aq) + 2 Cl⁻(aq)
            [Cl⁻] = 0.92 mol MnCl2/1L × 2 mol Cl⁻ / 1 mol MnCl2 = 1.8 M
The answer to this question is [Cl⁻] = 1.8 M

Which statement best describes the effect of color on energy absorption and reflection? 1. Light colors reflect more and absorb
fredd [130]
The statement which best described the effect of color on energy absorption and reflection is this: LIGHT COLORS REFLECT MORE AND ABSORB LESS THAN DARK COLORS. Black color absorbs all incident radiations while white color reflects all incident radiations; all other colors fall in the midst of these two colors.
