Document Summary
Atoms of the same element with different mass number. Arrangement of all elements in a table based on. Molecule: two or more atoms held together in chemical bond that are electrically. Compound: a molecule that contains at least two atoms of different elements. Ion: atom/molecule attainment of stability by loss/gain of electron. Anion: negatively charged ions due to gain of electron by atoms. Cation: positively charged ions due to loss of electrons by atoms neutral. Bonding: combination of atoms of the same or different elements to achieve stable structure through the interaction of electrons in the valence layer/orbital. Ionic bonding: this is the transfer of electrons from one atom to another to achieve a. Electron is gained by one and lost by another. Covalent: this is the sharing of valence electron by two or more atoms to achieve a stable structure stable structure. Petrology: the study of the origin, composition, distribution and structure of rocks.
