Chemical Bonds Flashcards
What is an atom?
Smallest unit of element
What is an element?
Chemical substance that cannot be broken down
What are subatomic particles?
Protons, neutrons and electrons
What is a proton
Protons are tiny particles inside the center of an atom, called the nucleus. They have a positive charge (+1) and help determine what kind of element an atom is.
Neutron define now.
A neutron is another type of subatomic particle found in the nucleus of an atom. However, neutrons have no electric charge
What is an electron
An electron is a tiny particle that orbits around the nucleus of an atom. Electrons have a negative charge (-1) and are much lighter than protons and neutrons.
What are valence electrons
Amount of electrons needed to fill outer energy level
What are ionic bonds
An ionic bond is when one atom gives an electron to another atom, and the resulting positive and negative ions attract each other.
Ion meaning
charged atom
What is electronegativity
Pull of electrons to an atom.
What is a cation
A cation is a type of ion that carries a positive charge.
Anion
An anion is a type of ion that carries a negative charge.
levels of electrons
Maximum of electrons for each level
1. Can hold up to 2 electrons.
2 Can hold up to 8 electrons.
Third energy level: Can hold up to 18 electrons.
Fourth energy level: Can hold up to 32 electrons
What is a solvent
Does the dissolving
Ph stands for
Parts per Hydrogen
