Chemistry Flashcards
what are Subatomic Particles and what are the 3 types
Particles that make up an Atom
Protons
Neutrons
Electrons
What charge are protons and where are they located
Positive charge
In the Nucleus
What charge are Neutrons and where are they located
Neutral Charge (No charge)
In the Nucleus
What charge are electrons and where are they located
Negative Charge
In the Outer Shells around the Nucleus
What charge are Atoms and why
Neutral
They have the same amount of Protons and Electrons
What is Atomic Number
Number of Protons in Nucleus
If Atom is neutral, it is also the number of Electrons
What is the Nuclear Charge
The electric charge of an atoms nucleus
Equal to the number of protons , because there is a positive charge in the nucleus
What are the 3 types of Elements
Metal (Left)
Non-Metals (Right)
Metalloids (Staircase)
What are Ions
Electrically charged particles created when atoms gain or lose electrons
Metal atoms transfer electrons to create positively charged ions (Cations)
Non Metal Atoms take in electrons to form negatively charged ions
(anions)
What are Multivalent Metals
Metals that can form ions in more than one way
What are Valence Electrons
The Electrons in the outermost shell
What is a stable octet
The arrangement of eight electrons in the outermost shell
What is a Valence shell
The outermost shell that contains electrons
What is an Ionic Compound
compound that contains positive ions and negative ions
Metal + Non-Metal
What is Ionic Bonding
When one or more electrons transfer from a metal atom to a non metal atom
