what is the relationship between atoms and molecules in a gas?

Electrostatic forces hold atoms together in molecules—like the two hydrogen atoms held together in H2 gas. Electrostatic forces also hold electrons and protons together in the atom. The attraction between negatively charged electrons and positively charged protons in an atom give the atom its structure.

The atoms in a molecule are joined by covalent bonds . The atoms always join in fixed ratios and molecules have a specific formula, eg H 2O or N 2. There are molecules of compounds (eg CH 4) and molecules of elements (eg O 2).

Atoms of different elements can combine to make new substances. A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.

An atom is made up of electrons, protons, and neutrons, split between an electron cloud and a nucleus. A molecule is something like H2O(water) and is made up of atoms. A cell is made up of atoms and molecules.

Chemical bonds hold atoms together in a molecule. Intermolecular forces such as hydrogen bonding allow molecules to attract each other but not with the strength of bonding within the molecule.

What is the relationship between the atomic molecular theory and kinetic molecular theory? Summary: A pure substance is made of one kind of substance and can be either an element or a compound. The kinetic molecular theory describes matter as made up of tiny particles in constant motion.

An atom is the smallest amount you can have of an element whereas a molecule is the smallest amount you can have of a compound.

Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.

An atom is the smallest amount you can have of an element whereas a molecule is the smallest amount you can have of a compound. A compound is made of atoms.

Originally Answered: What is the difference between air and gas? Air is a collection of different gases. Mainly nitrogen, and then oxygen. Gas is loosely bound atoms of an element or collection of such in compounds above the temperature required to make them liquid, and colder to make them solid.

PRESSURE: VOLUME RELATIONSHIPS IN GASES (BOYLE'S LAW) The inverse relationship between pressure and volume of gases such that as pressure increases, volume decreases by the same fraction of change; Temperature and number of molecules remain constant.

Matter is anything that occupies space and has mass. what is the relationship between elements and atoms? Elements are substances that cannot be broken down chemically into simpler kinds of matter. Atoms are simplest particle of an element that continues to have all the properties of that element.

A gas, on the other hand, has a vol- ume that changes to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.

Atoms are held together by bonds in a molecule. 4. a) What does is mean when two atoms are touching in the drawing of Model 1? The atoms are chemically bonded into a molecule (compound).

Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. The constituent elements are represented by their chemical symbols, and the number of atoms of each element present in each molecule is shown as a subscript following that element's symbol.

In general, electrons can be shared between atoms (a molecular bond) or electrons can be completely removed from one atom and given to another (an ionic bond). Molecules have molecular bonds. Nitrogen gas (N2) is a molecule because the bond between the nitrogen atoms is a molecular bond.
