Name the subatomic particle(s) that affect the mass of the atom.
Which side of the periodic table are metals found?
Left side
What is the charge of a cation?
Positive
******** TRIPLE TROUBLE ********

(must be in English, someone from another team will fact check/time!)
300 points!
In which part of the atom will you find electrons?
orbitals/shells
How many electrons would a neutral sodium atom have?
11
What are columns (up and down) of the periodic table called?
Groups

What was Dmitri Mendeleev's favorite fish?
2Na :)
What subatomic particle will change the isotope but not the element?
neutron
Name an element with 8 valence electrons.
Ne, Ar, Kr, Xe, Rn, or Og
Period 3
******* DAILY DOUBLE ************
Which letter does not appear anywhere on the periodic table?
J
A group VI element will become a(n) _____________ to have full valence shell.
In nuclide notation, where is the mass number indicated?
Top left side of the chemical symbol.
How many core electrons does phosphorous have?
10
What is the charge of an atom that has lost 3 electrons?
+3
Which group(s) contain the most reactive elements?
Group I and group VII
How many chlorine atoms bond with calcium to form calcium chloride?
2
They have the same amount of protons.
Which has more valence electrons?
Na+ O- P2-
Na+
What element has 2 more neutrons and 3 more protons than chlorine?
potassium
Which part of the periodic table (top/bottom, right/left) will have the largest atoms (biggest radius)? (bonus if you can tell us why!)
The bottom left corner (francium).
Because there are less protons "pulling" the outer electrons closer to the nucleus. There are more protons in elements on the right side, so they can 'keep' the electrons closer which decreases the radius of the atom.
Why do the atoms in an ionic bond stick together?
Because they have opposite charges.
How many protons, electrons, and neutrons are in 87Sr2+ ?
38 protons, 36 electrons, 49 neutrons
How many electrons would Boron need to gain or lose in order to have a full valence shell?
lose 3
