periodic table
What does the periodic table tell us about an element.
It tells us the element's name symbol,atomic number, and atomic mass
What is weather?
Wearther is the condition of the atmosphere at a certain place and time,like temperature, rain,wind, and clouds.
What is a chemical equation?
A chemical equation shows what happens in a chemical reaction using symbols and formulas.
What is a force?
A force is a push or pull that can change the motion of an object.
What is an energy pyramid?
An energy pyramid is a diagram that shows how energy flows through different levels of a food chain.
How are elements arranged on the periodic table?
They are arranged by atomic numbers, from smallest to largest.
What is the diffrence between weather and climate?
Weather is what happens day to day,while climate is the average weather over a long period of time.
What so the reactants and products mean in an equation?
Reactants are the starting substances, and products are the new substances that are formed.
What is motion?
Motion is when an object changes its position over time
What is found at the bottom of an energy pyramid?
Producers, like plants, are at the bottom because they make their own food using sunlight.
What is an atomic number?
The atomic number is the number of protons in an atom.
What causes wind?
Wind is caused by diffences in air pressure. Air moves from high pressure to low pressure.
What does it mean to balance a chemical equation?
It means making sure the same number of each type of atom is on both sides of the equation.
What is gravity?
Gravity is a force that pulls objects toward each other, especially toward the Earth.
What happens to energy as you move up the pyramid?
Energy decreases as you move up each level of the pyramid.
Were are metals and nonmetals found?
Metals are on the left side, and nonmetals are on the right side of the table.
What is the main type of precipitation?
Rain,snow,sleet,and kail
What does the arrow mean in a chemical equation?
It means “produces” or “yields,” showing the direction of the reaction.
What is friction?
Friction is a force that slows down or stops motion when two surfaces rub against each other.
What are consumers in an energy pyramid?
Consumers are organisms that cannot make their own food and must eat other organisms for energy.
Why are elements in the same group similar?
They are similar because they have the same number of outer electrons, so they act alike in reactions.
What tool is used to measure temperature?
A thermometer.
What does it mean to balance a chemical equation?
Balancing a chemical equation means making sure there are the same number of each type of atom on both sides of the equation.
. What happens when two forces act on an object in opposite directions?
The object will move in the direction of the stronger force, or not move if the forces are equal (balanced).
Why are there fewer organisms at the top of the energy pyramid?
There is less energy available at higher levels, so fewer organisms can survive there.
