Chapter 2 Structure Of Matter (Bushong) Flashcards
What are the three fundamental particles of atom
Proton, neutrons, electrons
Which atomic particles are found in the nucleus
Protons and neutrons
What is the electrical charge of a proton
Positive
What is the electrical charge of a neutron
Neutral
What is the charge of an electron
Negative
What is the ideal charge of an Atom
Zero, electrically neutral, no charge. Electrons and protons cancel each other’s charges out
How does the charge of an atom become positive
It loses an electron
How does the charge of an atom become negative
The atom gains an electron
What is a negative ion
Negative ions are created when a molecule gains a negatively charged electron
What is a positive Ion
Positive ions are created when a molecule gains a positively charged electron
Defined binding energy
The energy that holds an atom together
The electronic binding energy depends on what
Proximity to nucleus
Where is the binding energy the strongest
closest show to the nucleus
When is binding energy the weakest
In the farthest shell from the nucleus
How are you electron shells named
Starting K closest to the nucleus and ending at P, going alphabetically.
