<u>The answer is B. Gas molecules are in Constant Motion.</u>
This is supported by the Kinetic Theory of Gases, which it states that the gas particles are in constant random motion, colliding with the container that it's in.
Answer:
As we read from left to right across the periodic table atomic numbers are increased by one each of element.
Explanation:
As we move from left to right across the periodic table the atomic number is increased by one and the number of valance electron in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.
Answer:
6 valence electrons
Explanation:
The atom you have given is a sulfur atom. It has 6 valence electrons.
The answer is 4.
Gases have low densities, because of the increased space between hight-energy particles.
Most clouds are white. That's because water and ice particles that make up a cloud have just the right amount and sizes to scatter light in all possible wavelengths. When light of practically all wavelengths combine, the result is white light.
