PLEASE HELP!!
Helium is a gas at room temperature. Describe the arrangement and movement of helium molecules.
Answers
Answer:
Gases, such as the air or helium inside a balloon, take the shape of the containers they're in. They spread out so that the space is filled up evenly with gas molecules. ... This means they move faster and have more frequent and harder collisions inside of the balloon.
Question: Helium is a gas at room temperature. Describe the arrangement and movement of helium molecules.
Answer: It take up the shape of the object its in.
Info about helium: Helium only has 2 electrons and therefore it has a configuration of 1s2. Because the 1s orbital is full with 2 electrons and any additional electrons would go in a new energy level. The electron configuration for Helium shows a full outer shell and is Helium is therefore called a Nobel Gas.
Extra Information: Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
