A subatomic particle that has a negative charge?
What is an electron.
100
How many elements are on the periodic table?
What is 118.
100
What is an isotope?
What is different pairs of an element that have the same number of protons, but different neutrons.
100
If a sodium atom with 11 electrons meets a chlorine atom with 17 electrons what will happen?
The sodium atom will give its extra electron to the chlorine so that they will have full shells.
100
How many elements are there on the periodic table of elements?
What is 118.
200
Subtract the atomic mass from the atomic number to get this particle.
What is the neutron.
200
Which scientist came up with the periodic table?
Dmitri Mendeleev.
200
Radioactive decay.
What is when an isotope loses neutrons.
200
How do you show an atom that has given it's extra electron?
What is you put a plus after the atomic symbol; it becomes positive.
200
What element on the table has an atomic mass of 1?
What is Hydrogen (H)
300
Which particle decides what element an atom is?
What is the proton?
300
How many periods are there on the periodic table?
What is seven.
300
Why are atomic mass usually never an even number.
What is isotopes; they make the element uneven.
300
Ions and Anions are relatively where on the periodic table.
What is the left and right sides.
300
How many metals are there on the periodic table?
What is 91.
400
Which subatomic particles contribute the most to the atomic mass of an element?
What are protons and neutrons.
400
How was the periodic table changed when it was re devised.
What is by the atomic number.
400
What is the process of using radioactive decay to figure out the age of an object?
What is carbon dating.
400
What are the two main types of bonding?
What is covalent and electrovalent.
400
How many of the elements are noble gasses?
What is six.
500
Which subatomic particle is involved in chemical bonding?
What is an electron.
500
How was Mendeleev's model of the periodic table laid out?
What is by the atomic mass.
500
What is the proper way to notate an isotope?
What is the first letter of the element, a dash then the element's mass number. Ex: U-238
500
Where are covalent bonds; which are usually strong, weak?
What is in water.
500
What group are the noble gasses found in?
What is Group 18.
