Answer: Option (c) is the correct answer.

Explanation:

It is known that period number of the periodic table helps in determining the number of shells present in the elements of the respective period.

For example, as potassium and copper both lie in period four which means that n = 4.

That is, the number of shells present in both potassium and copper is 4.

Whereas when elements are present in same group then they contain same number of valence electrons. Due to which elements of the same group tend to show similar chemical properties.

Therefore, we can conclude that potassium (K) and copper (Cu) are both in period 4. They both have four electron shells.

Which statement describes effusion?
frez [133]

Answer:

It occurs when a gas passes through a tiny hole.

Explanation:

Effusion is a term used to describe when a gaseous molecule in a container passes or escapes through a tiny/small hole. Effusion and diffusion are two properties of gases that are often used interchangeably, however, they differ.

Effusion differs from diffusion in the sense that the gas passes through a TINY HOLE that is smaller than the normal path. This is contrary to when gas disperses throughout a container as in diffusion.

Please give a brief explanation on all the types of clouds, like stratus, Stratocumulus and etc
blondinia [14]
When water on land or in the ocean evaporates - turns from a liquid to water vapor - it rises. The water vapor cools and turns back into a liquid in the shape of tiny droplets. The result is clouds, unless it's on the ground - then we call it fog. When enough droplets get together they fall to the ground as rain or if it's very cold, they freeze and fall down as snow, sleet or hail. Clouds play an important role in the energy balance of Earth. They cool the earth by reflecting sunlight back out to space. How else do you think astronauts see where they are going? More importantly, clouds replenish our water supply. It's a never-ending cycle but one that keeps the earth balanced. You can tell a lot by looking at a cloud's shape, size and texture. Clouds are put into categories according to their shape, how high they are in the sky, their size, how fast and in what direction they are moving, etc. The three different types of clouds are high clouds (because they are high in the sky), medium clouds and low clouds (just over 10,000 feet high or 3 km.)
