When two or more atoms chemically join they form?Ī molecule is formed when two or more atoms join together chemically. The oxygen we breathe, for example, is a molecule of two oxygen atoms – O 2. That means they contain atoms of only one element. What has two or more atom that are bonded together?Ī molecule is usually two or more atoms held together with chemical bonds. A chemical reaction occurs when two or more substances are combined to form a new substance and cannot be separated back into its original substances. When one or more substance is combined?Ī mixture is created when two or more different substances are physically combined and can be separated back into its original substances. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. These electrons are simultaneously attracted by the two atomic nuclei. Which type of bond forms when two or more atoms share electrons?Ī covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. The group of atoms held together by covalent bonds is called a molecule. What is formed when two or more atoms are held together by covalent bonds? All compounds are molecules, but not all molecules are compounds. If atoms combine that are of two or more different elements, we call that a compound. When 2 or more atoms join together?Ī molecule is formed when two or more atoms join together chemically. The basic composition of a compound can be indicated using a chemical formula. When atoms combine through chemical bonding, they form compounds-unique structures composed of two or more atoms. When two or more atoms join together they form what? 6 What are two or more atoms joined by a chemical bond called?.5 When two or more atoms chemically join they form?.4 When one or more substance is combined?.3 Which type of bond forms when two or more atoms share electrons?. 1 When two or more atoms join together they form what?.
