How can hydrogen and oxygen can combine to form molecules?

Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. As the products of the reaction are at a lower energy level than the reactants, the result is an explosive release of energy and the production of water.

How do elements combine to make compounds?

When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).

How do atoms of different elements combine?

Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms. Atoms of same element can combine in more than one ratio to form two or more compounds. The atom is the smallest unit of matter that can take part in a chemical reaction.

What is it called when two or more elements are chemically combined?

Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.

When oxygen combines with hydrogen which substance is formed Quizizz?

Hydrogen and oxygen can combine in many ways to form different molecules. When Oxygen combines with hydrogen to make a molecule, water is always produced. Which of the following best explains the relationship between molecules and atoms. Molecules are made up of two or more atoms.

How do atoms bond together to produce new substances?

In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Why do atoms of different elements combine to form ionic compounds?

All chemical bonding is due to electrostatic attraction. When atoms combine through chemical bonding, they form compounds—unique structures composed of two or more atoms. The strong electrostatic attraction between adjacent cations and anions is known as an ionic bond.

Who said different elements combine together to form compounds?

Dalton proposed that each chemical element is composed of atoms of a single, unique type, and though they cannot be altered or destroyed by chemical means, they can combine to form more complex structures (chemical compounds).

Why do atoms combine together?

Atoms mainly combine to fill the outermost shell and they can combine with similar elements or different elements. Sometimes, they can achieve stability even after half-filled subshell. Electrons that are present in the outermost shell are known as valence electrons.

When same kind of atoms combine together chemically molecule of a an is formed?

1) When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound.

When these elements are combined a new substance is formed with new chemical and physical?

When two or more elements combine to form a new substance, it is called a compound. There are many different types of compounds, because atoms of elements combine in many different ways to form different compounds. Examples include water (H2O) and table salt (NaCl). The smallest part of a compound is a molecule.
