Atomic Structure
Name the 3 subatomic particles of an atom
What are proton, neutron and electron?
A vertical column on the periodic table is called this.
What are groups or families?
This element has 20 electrons.
What is calcium?
These types of elements are located on the right-hand side of the periodic table.
What are nonmetals?
I have 3 protons. Which element am I?
What is lithium?
This subatomic particle is located in the nucleus and has a positive charge.
What is a proton?
Fluorine, Chlorine, Bromine, and Iodine are all considered this.
What are Halogens?
This element is in Group 18 and has only 2 electrons.
What is Helium?
The periodic table is mostly made up of these types of elements.
What are metals?
I have 2 valence electrons and am in period 3. Who am I?
What is magnesium?
These 2 subatomic particles are found inside the nucleus of the atom.
What are protons and neutrons?
The vertical columns on the periodic table are organized by this.
What is the number of valence electrons?
This element has 31 neutrons.
What is Nickel?
The actinides and lanthanides are considered this.
What are transition or rare Earth metals?
I have 6 valence electrons and am in period 2. Who am I?
What is Oxygen?
This subatomic particle has changes in number when isotopes are created.
What is a neutron?
A period on the periodic table will tell you this.
What is the number of electron orbitals?
When you subtract the atomic number from the mass number, you find the number of this.
What are neutrons?
The elements that contain properties of metals and nonmetals are called this.
What are metalloids?
I am in period 3 and am a Nobel gas. Who am I?
What is Argon?
This subatomic particle changes in number to create ions.
What is an electron?
The group that an element with 2 valence electrons is called this.
What is the Alkali Earth Metals?
When an element has 19 protons and 19 electrons it is said to be
What is electrically neutral?
Very reactive metals in group 1 have how many valence electrons and want to do what with those valence electrons (2-part question)
What is one valence electron that they want to give away or lose?
I am in the alkali metals in the second row. Who am I?
What is lithium?
