Bond… Chemical Bond
The bond in NaCl forms because sodium loses one electron and chlorine gains one, forming these charged particles.
What are ions?
Elements in this vertical column share similar chemical properties.
What is a group (or family)?
This type of reaction occurs when two or more substances combine to form a single product.
What is a synthesis (combination) reaction?
KBr
What is potassium bromide?
This is the substance that does the dissolving in a solution.
What is the solvent?
A covalent bond where electrons are shared equally because the electronegativity difference is very small.
What is a nonpolar covalent bond?
This group 1 element is highly reactive and explodes in water; its symbol is K.
What is potassium?
A reaction that releases heat to the surroundings is called this.
What is an exothermic reaction?
N₂O₅
What is dinitrogen pentoxide?
This term describes a solution that contains the maximum amount of solute at a given temperature.
What is a saturated solution?
This type of bond forms when electrons are transferred from one atom to another.
What is an ionic bond?
This trend increases as you move from left to right across a period and measures an atom’s ability to attract electrons.
What is electronegativity?
In a redox reaction, the substance that loses electrons undergoes this process.
What is oxidation?
NH₄NO₃
What is ammonium nitrate?
The concentration unit defined as moles of solute per liter of solution.
What is molarity?
This type of bond involves atoms sharing electrons.
What is a covalent bond?
As you move down a group, atomic radius generally does this.
What is increases?
In the reaction 2H₂ + O₂ → 2H₂O, this substance is reduced.
What is oxygen?
PCl₅
What is phosphorus pentachloride?
Increasing temperature generally does this to the solubility of most solid solutes in water.
What is increases?
This type of intermolecular force occurs when hydrogen is bonded to N, O, or F and is attracted to a lone pair on another molecule.
What is hydrogen bonding?
This number tells you how many protons are in an atom’s nucleus.
What is the atomic number?
The minimum amount of energy required to start a chemical reaction is called this.
What is activation energy?
Li₃N
What is lithium nitride?
This property explains why oil does not dissolve in water.
What is polarity?
