Periodic Table Flashcards
1
Q
Define a chemical bond
A
A mutual attraction between two atoms resulting from the simultaneous attraction between their nuclei and the outer electrons. (The energy of the combined atoms is lower than that of the individual atoms resulting in higher stability.)
2
Q
Define covalent bond
A
The sharing of electrons between atoms to form molecules
3
Q
Define molecule
A
A group of two or more atoms that are covalently bonded and that functions as a unit
4
