Matter
Matter is defined as...
What is Anything with Mass and Volume (space)
The atomic mass is made up of what two sub-atomic particles?
What is protons and neutrons
Elements of the periodic table are arranged from left to right by
increasing atomic number
This number tells you how many protons are in an atom of an element.
What is the atomic number?
What is known as the building block of matter?
What is atoms
Which sub-atomic particle has the least mass?
What is the Electron?
Which family is the most reactive metals?
What are Alkaili Metals?
This is the smallest unit of an element that still has the properties of that element.
What is an atom?
Atoms make up what
What is Substance or Molecule
An atom contains 8 protons, 8 neutrons, and 8 electrons. What is its atomic number and mass number?
What are 8 and 16?
Which family is the most reactive nonmetals?
What are the Halogens?
A student mixes two clear liquids and observes bubbles forming and the temperature changing. These observations provide evidence that this has occurred.
What is a chemical reaction?
This change of state occurs when a gas loses thermal energy and becomes a liquid.
What is condensation?
An atom has 20 protons and 18 electrons. Explain why it has a positive charge.
What is it has two more protons than electrons, giving it a +2 charge?
Majority of elements on the periodic table are what type of material?
What are Metals?
This element is the most abundant element in the universe.
What is hydrogen?
When a substance changes from a solid directly into a gas without becoming a liquid first, this process occurs.
What is sublimation?
An unknown atom has a mass number of 23 and an atomic number of 11. How many protons, neutrons, and electrons does a neutral atom of this element have?
What are 11 protons, 12 neutrons, and 11 electrons?
How many groups are on the periodic table?
What is 8/18?
An element has 6 valence electrons. Based on its position in the periodic table, it is most likely to do this to become more stable.
What is gain 2 electrons?
