What is a substance made of the bonded atoms of two or more different elements?
Elements are the simplest complete chemical substances. Each element corresponds to a single entry on the periodic table. An element is a material that consists of a single type of atom. Each atom type contains the same number of protons.
What is it called when many atoms are bonded together?
A group of two or more atoms, bonded together is called a molecule. Molecules may also be referred to as compounds. An element is any chemical that is comprised of only one type of atom. This may be single atoms, or molecules. The oxygen we breathe is an element, and exists as two covalently bound oxygen atoms.
What has two or more atoms bonded together?
When two or more atoms chemically bond with each other, the resultant chemical structure is a molecule. Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed.
Which name is given to a pure substance made from more than one type of atom?
Compound. A pure substance made from more than one type of element chemically bonded together. Elements bond in fixed ratios and so can be represented by a chemical formula.
What is produced when two atoms combine?
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. When two hydrogen atoms combine with one oxygen atom, it becomes the compound water.
What substances are made up of atoms?
10 Cards in this Set
| Elements | A pure substance that is made entirely from one atom Eg: |
|---|---|
| Compounds | Are pure substances made up entirely from two or more elements that are chemically combined |
| Law of Conservation of Energy | Mass cannot be created nor destroyed in ordinary chemical of physical changes |
What is a substance made of one type of atom?
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
What is a substance composed of two or more atoms?
A compound is a pure substance made of two or more elements chemically combined in a set ratio. A compound may be represented by a chemical formula, which shows the elements in the compound and the ratio of atoms, CO2. What are the similarities and differences between a compound and a molecule?
What do you call two atoms that are bonded together?
Molecules. H2, N2, O2 are called di-atomic because they contain two atoms of the same element. Compounds are molecules that include more than one type of atoms. Q: What are atoms bonded together called?
How is a chemical bond formed in a substance?
substance made of atoms of different elements that are bonded together in a particular ratio Ion atom that has gained or lost one or more electrons Ionic Bond chemical bond formed through the electrical force btwn oppositly charged ions Covelant Bond chemical bond formed when two atoms share one or more pairs of electrons
Which is an element that cannot be broken down by chemical means?
Element substance made of only one type of atom that cannot be broken down by chemical means Compound substance made of atoms of different elements that are bonded together in a particular ratio Ion atom that has gained or lost one or more electrons Ionic Bond chemical bond formed through the electrical force btwn oppositly charged ions
