The negatively charged part of the atom.
electron 1 pt
The smallest part that an element can be broken down to and retain its physical and chemical properties.
atom 2 pts
The name given to the group of elements that are the most stable.
Noble gas 3 pts
When an atom gains or loses neutrons, it is called this.
Isotope. 4 pts
Properties of elements change periodically with the elements’ atomic number according to this.
Periodic law 5 pts
This part of the atom has a positive charge.
proton 1 pt
This part of the atom has a negative charge.
electron 2 pts
This part of the atom is in the center and includes protons and neutrons.
nucleus 3 pts
Draw a Bohr model for boron (B).
Is it possible for carbon (C) to have 7 protons? Explain your answer.
No. If it has 7 protons it is a different element. It is nitrogen (N). 5 pts
What is the name of the element with the symbol Cl?
Chlorine 1 pt
How many protons are in an atom of magnesium (Mg)?
12 2 pts
The atomic number of an atom, as it appears on the periodic table of elements, is the same as the number of ______.
Protons and electrons 3 pts
An atom of cesium (Cs) has 55 protons, 55 electrons and 78 neutrons. What is its atomic mass?
133 4 pts
An atom has 21 electrons. How many neutrons does it have?
24 5 pts
The horizontal rows on the periodic table are called ________.
Periods. 1 pt
The vertical columns on the periodic table are called ________.
Groups or families 2 pts
Most of the elements on the periodic table are to the left of the zigzag line and are classified as this.
metals 3 pts
Lithium (Li), sulfer (S), nickel (Ni) or germanium (Ge). Which of these is a metalloid?
Germanium (Ge) 4 pts
What do all the elements in group 17 have in common.
Similar reactivity or 7 valence electrons. 5 pts
The center of the atom is made of these.
1 pt Protons and neutrons
Metalloids have characteristics of both of these.
Metals and non-metals 2 pts
Metals can be described as good conductors of these.
Heat and electricity 3 pts
These 2 groups on the periodic table of elements are the most reactive.
4 pts Group 1 and 17. or The alkali metals and halogens
How does reactivity of the elements change as you move from group 1 to group 18.
5 pts Reactivity starts high, goes down, and then rises again to high in group 17. Group 18 has no reactivity.
Final Jeopardy Category Organization of the Periodic Table
Write your point wager on your board now. You can wager any amount from 0 points to your total points.
The elements in group 18, the Noble Gasses, are grouped together because they are stable. Why are they stable?
Their outer electron shell is full.
