Atomic Structure
The center of an atom is called this.
What is the nucleus?
This state of matter can be compressed the most.
What is gas?
This is what the horizontal rows on the periodic table are called.
What are periods?
Ionic compounds have this kind of melting point — high or low?
What is high?
This halogen is used in disinfectants and bleaches.
What is chlorine(Cl)?
This subatomic particle has no charge.
What is a neutron?
This is the freezing point of water in Fahrenheit.
What is 32°F?
This is what the vertical columns on the periodic table are called.
What are groups?
Ionic compounds are usually this state at room temperature.
What is solid?
This noble gas is used to fill balloons.
What is helium(He)?
This is the name for the outermost electrons.
What are valence electrons?
This is the term for the amount of matter in an object.
What is mass?
These elements have properties of both metals and nonmetals.
What are metalloids?
This term describes the ability of a substance to allow electricity to flow.
What is conductivity?
This halogen is used in daily life, most likely found in mouthwashes and toothpastes.
What is fluoride(F)?
This is the number of protons in an atom, and it defines the element.
What is the atomic number?
This is what happens to the speed of particles when temperature increases.
What is they move faster?
Elements in the same group have this in common.
What is the same number of valence electrons?
Ionic compounds do not conduct electricity in this state because ions are fixed.
What is solid?
This element is necessary for healthy bones and teeth and is found in milk.
What is calcium(Ca)?
These are atoms of the same element with different numbers of neutrons.
What are isotopes?
This change of state turns gas directly into a solid.
What is deposition?
As you move from left to right across a period, this happens to atomic number.
What is it increases?
Ionic compounds are made of metals combined with these elements.
What are nonmetals?
This is the most abundant element in the universe.
What is Hydrogen(H)?
