Structure of an atom
Atoms are made up of these three kinds of particles.
What are protons, neutrons, and electrons?
Polarity results from a difference in this.
The lower the potential energy of the bond, the _____ the bond is.
What is stronger?
This kind of interaction is when atoms share electrons equally.
What is a nonpolar covalent bond?
This word describes a neutral atom that has LOST an electron.
What is a cation?
This element has 6 protons.
What is carbon?
This quality of an atom increases across a row in the periodic table.
What is electronegativity?
The higher the potential energy, the _____ the bond is.
What is weaker?
This kind of interaction involves electrons that are not shared equally.
What is a polar covalent bond?
This word describes a neutral atom that has gained an electron.
What is an anion?
These elements are the most abundant on Earth.
What is hydrogen, oxygen, nitrogen, and carbon?
Water is a _____ molecule.
What is polar?
A weak bond would require ____ energy to break.
What is little?
This bond is between atoms with very different electronegativities- hint: stealing!
What is an ionic bond?
Atoms prefer to fill up their valence shell because of this rule.
What is the octet rule?
Electrons move around in this structure.
When a molecule loves water, we call it this.
What is hydrophilic?
A strong bond would require ______ of energy to break.
What is "a lot"?
This bond forms between a hydrogen atom and a more electronegative atom.
What is a hydrogen bond?
Atoms of the same element that have a different number of neutrons are called this.
What are isotopes?
The first shell of electrons holds this amount of electrons.
What is 2?
A hydrophobic molecule does not bond with water because of this quality.
What is nonpolar?
A strong, covalent bond has ____ potential energy.
What is low?
What is Van der Waals forces?
This man developed the periodic table.
Who is Dmitri Mendeleev?
