Reading the Periodic Table
This element has the atomic number 33.
What is arsenic (As)?
This characteristic of metals gives them their shine.
What is luster?
This family contains the element radium (Ra).
What are alkaline earth metals?
What is increases?
This part of the atom contains the protons and neutrons, contributing to the majority of the atomic mass.
What is the nucleus?
In a neutral atom of this element, there are 82 electrons.
What is lead (Pb)?
Alkali metals have a tendency to explode in water. We would say that alkali metals are very _____.
What is reactive?
This family is found in Group 17 of the periodic table.
What are halogens?
Moving in this direction on the periodic table, the atomic size increases.
What is down? OR What is left?
This element has 6 protons, 6 neutrons, and 6 electrons.
What is carbon (C)?
This element is found in Group 10, Period 6.
What is platinum (Pt)?
This property of metals refers to an element's ability to transfer heat and electricity.
What is conductivity?
This family of elements has properties of both metals and non-metals.
What are metalloids?
Between magnesium (Mg) and barium (Ba), this metal is generally considered more reactive.
What is barium (Ba)?
These two subatomic particles contribute to the overall mass (amu) of an atom.
What are protons and neutrons?
This alkali metal is found in Period 4 of the periodic table.
What is potassium (K)?
Elements with similar properties share the same number of this subatomic particle.
What are valence electrons?
This family of metals is typically used in jewelry and construction.
What are transition metals?
This element is the most reactive non-metal on the periodic table.
What is flourine?
The number of this subatomic particle is found by subtracting the number of protons from the atomic mass.
What are neutrons?
This element is found in Period 2 and has 3 valence electrons.
What is boron (B)?
Uranium (U), Radium (Ra), and Radon (Rn) all share this elemental property.
What is radioactivity?
This family of elements is non-reactive due to its full valence shell.
What are noble gases?
The decrease in atomic size moving across a period/row on the periodic table is largely due to an increase in this subatomic particle. (Hint: it increases the pull of electrons towards the center of the atom)
What are protons?
While the atomic masses of carbon-12 and carbon-13 differ, what do they have in common?
What is the number of protons?
