II. Atoms and Atomic Orbitals
A- Neutral Atom 1- Contains a sum at its core. a- The nucleus is an memberic number 18a of positively charged protons and indifferent(p) neutrons. b- The nucleus is surrounded by negatively charged electrons, which are equal in number to the protons. 2- Ion a- Occurs when protons and electrons are not equal. B- Anion 1- negatively charged atom or molecule. C- Cation 1- Positively charged atom or molecule.

D- Ionization Potential 1- Form of Energy. 2- Energy unavoidable to take an electron away from an atom. 3- Forms a cation. 4- In general, increases as you go up the column and across a row.

E- eight-spot Rule 1- An atoms goal is to achieve the electron configuration of the imposing floates. 2- The octet rule helps us understand that we need to film certain fonts to reach a stable configuration.

3- First shell: 1s holds 2 electrons. 4- Second shell: 2s and 2p are subshells. a- They hold a total of 8 electrons.



b- 2 electrons in 2s and 6 electrons in 2p. 5- Please look at Figure 1.1 on pageboy 4 in the text.

F- Electron Affinity 1- This is a way of measuring the tendency of an atom or molecule to allow in an electron. 2- It is measured in electron volts (eV). 3- Noble gases = low electron affinity. 4- When you add an electron to an atom and complete the noble gas configuration = high electron affinity. a- A prime vitrine if this is fluorine. See Figure 1.2 on page 4 in the text.

G- Mass number (W) and atomic number (Z) writing convocation (zwC) a- The mass number represents the number of protons and neutrons in an elements nucleus, and is symbolized by a superscript W in count of the element symbol. 1-...If you want to get a full essay, beau monde it on our website: Orderessay
