Chapter 2 Atoms Molecules Ions Pdf Ion Atoms Covalent bond: results when two atoms share several, but usually two, elections often occurs between a non metal and another non metal molecule: two or more atoms joined together covalently. 2 ions and ionic compounds: ions= formed when an atom or a molecule gains or loses an electron or electrons cations= positively charged ions anions= negatively charged ions charges of ions are written in the format element ^ sign example: fe^3 s^2 po4^3 for ions with charges 1 and 1 the number to the power is taken out.
Ppt Chapter 2 Atoms Molecules And Ions Powerpoint Presentation Ions, on the other and, have extra electrons added or removed to form anions (negatively charged ions) or cations (positively charged ions). the sharing of electrons between atoms is a covalent bond. Ex: all atoms with 6 protons are carbon and all carbon atoms have 6 protons. properties of ions are quite different than the neutral atom (nacl) so pay close attention. naturally occurring boron consists of two isotopes: 10 b (10 amu) and 11 b (11. amu). the average atomic weight of boron is 10 amu. Students will be able to state the number of protons, electrons and neutrons in neutral atoms, ions, and isotopes. students will understand the derivation and meaning of atomic mass and be able to calculate weighted average masses from isotopic data. Chapter 2 notes atoms, molecules and ions 2.1 the early history refer to the chemistry history timeline for this chapter 2.2 fundamental chemical laws law of conservation of mass "mass is neither created nor destroyed" translation: in ordinary chemical reactions, the total mass of the reactants is equal to the total mass of the products.

Chapter 2: atoms, molecules, and ions (ch2 chang, chs 0 and 2 jespersen) atoms are the basic building blocks of matter. they are the smallest particles of an element that retain the chemical identity of the element, or, the basic unit of an element that can enter into chemical combination. s atomic theory can be summarized by these. Study with quizlet and memorize flashcards containing terms like intesive properties, extensive properties, physical properties and more. Elements are composed of atoms. all atoms of an element are identical in mass and other properties, but are different from the atoms of any other element at: law of definite proportions. Each element is composed of extremely small particles called atoms. all atoms of a given element are identical to one another in mass and other properties, but the atoms of one element are different from the atoms of all other elements.
