An atom becomes stable if it has a full and complete ring. 2 of the choices are wrong off the start because you can't gain electrons and have a net positive charge, nor can you lose electrons and have a net negative charge. That leaves us with Option A or D. As I said earlier, an atom becomes stable if it has a full and complete ring. Obviously, if you lose 3 electrons from the last ring, the atom would be stable (because the 2nd ring is now full), and it also would have a net positive charge because it lost electrons.

4. True

5. The amplitude of the ripples decreases as the circumference of the circle increases.

A wave is a disturbance that moves energy from one place to another.

Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each travelling in a wave-like pattern at the speed of light. Hence, the statement is true.

As the disturbance moves outwards the energy it carries is spread over a larger and larger region called the wavefront. For example, the ripples in the water lie in a circle with an ever-increasing circumference. The amplitude of the ripples decreases as the circumference of the circle increases.

Which of the following is a correct lewis structure for sulfur dioxide, so2?

pshichka [43]

The correct Lewis structure of SO2 is the Lewis structure that shows all the 12 valence electrons in the molecule.

A Lewis structure shows the number of valence electrons on the valence shell of all the atoms in a compound. The electrons are shown as dots around the symbol of each element or a dash to indicate shared electrons in a covalent bond.

Looking at the Lewis structure of SO2 attached to this answer, we can see the twelve valence electrons in the molecule and how they are distributed around each atom as shown.
