and Shapes
This theory is used to predict the shapes of molecules.
What is VSEPR theory?
This particle of the atom has a positive charge.
What is a proton?
This is the group number for the noble gases on the periodic table.
What is Group 18?
H₂O
What is water?
Compounds with this type of bond typically have high melting points and conduct electricity when dissolved in water.
What are ionic bonds?
A single bond represents this many shared electrons.
What are two electrons?
The atomic number of an element tells you this about its atoms.
What is the number of protons?
As you move down a group in the periodic table, this atomic property increases.
What is atomic radius?
NaCl
What is salt?
A covalent bond forms when atoms do this with electrons.
What is sharing electrons?
The shape of a molecule with two bonded atoms and no lone pairs on the central atom.
What is linear?
This subatomic particle has no charge and is found in the nucleus.
What is a neutron?
This is the term for the energy needed to remove an electron from an atom.
What is ionization energy?
CO₂
What is Carbon Dioxide?
This type of covalent bond involves unequal sharing of electrons.
What is a polar covalent bond?
The electron geometry of a molecule with four bonding pairs.
What is tetrahedral?
The mass number of an atom is calculated by adding these two particles together.
What are protons and neutrons?
Elements in this group have a single electron in their outermost shell.
What are alkali metals(group 1)?
Fe₂O₃
What is Iron III Oxide?
Ionic bonds typically form between these two types of elements.
What are metals and nonmetals?
The molecular shape of H₂O.
What is bent/angular?
Isotopes of the same element differ in the amount of this subatomic particle.
What is the number of neutrons?
This element has the highest electronegativity on the periodic table.
What is fluorine?
SO₄
What is sulfate?
Covalent bonds tend to form between these types of elements.
What are nonmetals?
