Elements
What is the very first element on the Period Table?
What is Hydrogen
Elements on the periodic table are strictly arranged by this increasing number.
What is atomic number?
This dense, central core of an atom.
What is the nucleus?
This property causes an object to resist any change to its current state of motion.
What is inertia?
This term describes a characteristic of a substance that can be observed or measured without changing what it is.
What is a physical property?
This gas is the most abundant element found in Earth's atmosphere
What is Nitrogen?
Elements in the same vertical group or family always share the same number of these outermost electrons.
What are valence electrons?
This subatomic particle has zero electrical charge.
What is a neutron?
If you keep the force the same but increase the mass, this value will decrease.
What is acceleration?
This law states that matter cannot be created or destroyed in a chemical reaction.
What is the Law of Conservation of mass?
What is the last natural element on the Periodic Table?
What is Uranium
When you move left to right across a period, this atomic property decreases because a stronger nuclear charge pulls the electron cloud closer.
What is atomic radius?
This term describes an atom that has gained or lost one or more electrons, making it have a positive or negative charge.
What is an ion?
This is the metric unit used to measure force.
What is a Newton?
This type of heat transfer occurs through the bulk movement of fluids or gases.
What is Convection?
This group of elements has properties of both metals and nonmetals.
What are Metalloids?
This highly reactive group of metals occupies Column 1 on the far left side of the table.
What are the alkali metals?
This term describes atoms of the same element that have different numbers of neutrons.
What are isotopes?
This force attracts any two objects with mass, and its strength depends on how heavy the objects are and how far apart they sit.
What is gravity?
This type of change alters the appearance of a substance without changing its chemical identity.
What is a physical change?
This element is the first member of the alkali metal family and is used in rechargeable batteries.
What is Lithium
To find the number of neutrons in an atom, you subtract the atomic number from this value.
This region of an atom takes up basically all of its volume but has little to none of its total mass.
What is the electron cloud?
If a food cart is going down the sidewalk at a net force of 30 Newtons causes it to accelerate down a sidewalk at 5 meters per second squared. How many Kilograms of weight does it have? (SOLVE)
What is 6 kilograms?
This number on the pH scale represents a completely neutral substance like pure water.
What is 7?
