Write the number of protons, neutrons and electrons in Na with a mass no of 23

The following slides should help you with your revision, but should not be your only form of revision. Remember to use your notes, a textbook, websites and Past Papers to help you. You can also ask a chemistry teacher for help too.

They will questions the results because the scientist changed more than one variable at a time.

1. A scientist ran an investigation to study the effects of electron arrangement and number of neutrons in an atom on chemical behavior. The scientist varied both factors at the same time. How will other scientists weigh the results?.

Electrons and Ions (p. 37) (Date)

Electrons and Ions (p. 37) (Date). Target: I know what an ion is and how to find the number of electrons. Number of electrons is usually the same as the number of protons, unless the atom has a charge Charged atoms are called ions

How are electrons arranged?

1 st shell. 2 nd shell. 3 rd shell. How are electrons arranged?. Electrons are not evenly spread, but exist in layers called shells. (The shells can also be called energy levels). The arrangement of electrons in these shells is often called the electron configuration.

Covalent Bonding

Covalent Bonding. When Atoms join they do so by a Chemical Bond When non - metal atoms join they form a Covalent Bond When Atoms join it is their outer electrons that are directly affected Remember that atoms join so as to try and achieve their nearest most stable electron arrangement .
