Mаtch the fоllоwing terms with their definitiоns. Write ONLY the NUMBER thаt is in the column on the left of the definitions in the аnswer field next to each term. (There are more definitions than needed.) Terms: electronegativity - [7] lattice energy- [10] pressure - [5] sigma bond- [2] Definitions 1 model that describes the changes in the atomic orbitals of an atom when it forms a covalent compound 2 covalent bond formed by overlap of atomic orbitals along the internuclear axis 3 volume of 1 mole of gas at STP, approximately 22.4 L for gases behaving ideally 4 covalent bond in which electrons are not shared equally 5 force exerted per unit area 6 covalent bond formed by side-by-side overlap of atomic orbitals 7 tendency of an atom to attract electrons in a bond to itself 8 hypothetical gas whose physical properties are perfectly described by the gas laws 9 covalent bond in which electrons are shared equally or almost equally 10 energy required to separate one mole of an ionic solid into its component gaseous ions
