Cards in this deck (24)
- 1What is an atom?An Atom is the smallest particle of an element that still has the properties of that element
- 2Can Atoms be seen with a microscopeNo. They are too small
- 3The properties of an atom determine what?The properties of the element
- 4What is an atom's center calledThe nucleus
- 5What charge does a neutron have?No charge. It is Neutral
- 6What charge does a proton have?A Positive Charge
- 7What charge does an Electron have?An negative charge
- 8How can you tell the number of Protons an Atom has on the periodic tableLook at the element number at the top. This will tell you the number of Protons
- 9Larger atoms are found on what side of the periodic table?On the right side
- 10Smaller atoms are found on what side of the periodic table?The left side
- 11How are the columns in the periodic table arranged?The columns are arranged so that elements with SIMILAR PROPERTIES are in the same column
- 12What is a Molecule?A Molecule is the smallest particle of s substance that still HAS THE PROPERTIES OF THAT SUBSTANCE
- 13What is the difference between and atom and a molecule?A molecule is made up of two or many atoms. These atoms come from the same elements. For example, an OXYGEN MOLECULE IS MADE UP OF TWO OXYGEN ATOMS.
- 14What is a compound?A compound is a type of matter made up of a COMBINATION OF ELEMENTS. For example, Water is made up of two hydrogen atoms and one oxygen atom - (H2O)
- 15How are compounds formed?They are formed by SHARING ELECTRONS or they are formed when PARTICLES ARE HELD TOGETHER BY OPPOSITE CHARGES
- 16What element does Salt have in it?a Metal element
- 17salts form what?crystals
- 18why does salt form crystals?Salt forms crystals when charged particles arrange themselves in a regular geometric patterns
- 19what kind of temperature is needed to melt salt?high temperatures
- 20What is the formula for salt?Na (sodium) and Chloride (Cl)
Sodium Cloride
(NaCl) - 21Most table salt is made of sodium chloride. What is sodium in it's pure form?A soft silvery metal
- 22Most table salt is made of sodium chloride. What is chloride in its pure form?It is called Chlorine and it is a yellow poisonous gas.
- 23what happens if you put pure sodium in water?It can cause an explosion
- 24What happens when you put chlorine and sodium together?you get SALT!
(sodium chloride)
NaCl
