Classes
These are 3 bunches of groups on the periodic table, that are grouped together based on similar properties. What are they?
What is Metals, Nonmetals, and Metalloids
The term for each new row on the periodic table is called this:
What is a period?
Columns in the periodic table of elements are called these:
What are groups in the periodic table?
This subatomic particle has a negative charge and is found outside the nucleus?
What is an electron?
According to Libretexts.org, specific patterns that are present in the periodic table that illustrate different aspects to a certain element are known as these:
What are periodic trends?
This is the smallest class on the periodic table, consisting of only 7 elements:
What are metalloids?
What period of the Periodic Table is Potassium located on?
What is Period 4?
Although the elements in each group have similar properties, the arrangements of the elements into groups in the periodic table is mainly based on this:
What is the number of outer-ring electrons?
The number of protons and electrons in an atom tells you what element it is. Where can you find this number?
What is the atomic number?
This trend is an atoms tendency to attract electrons, the trend increases from left to right and from top to bottom on the periodic table:
Elements in this class share the ability to conduct electricity, relatively high melting points as well as being shiny, ductile and malleable:
What are metals?
This period on the periodic table contains only 2 elements, Hydrogen and Helium, as these are the only 2 elements with a single electron shell.
What is period 1 on the periodic table of elements?
The element cobalt, having 9 valence electrons, belongs to this periodic group:
An element in Period 3 of the periodic table will have this many electron shells.
What is 3 electron shells?
This periodic trend is 1/2 the distance between the nuclei of 2 atoms, it decreases from left to right and increases from top to bottom:
This metal element is a liquid at room temperature
What is Mercury?
This period on the periodic table contains 32 elements, most of which belong to either the lanthanide or transition metals family:
What is period 6 on the periodic table?
All elements in this periodic group are colorless, odorless gases, known as the noble gases.
What is group 18?
Elements in the same group (column) of the periodic table tend to have similar chemical behavior because they have similar numbers of these.
What are outer-ring (valence) electrons?
Belonging to the non-metal class, this element has the highest melting point of all the elements on the periodic table:
What is carbon?
This metalloid element is often used as a semi-insulator in computer microelectronics industries:
What is silicon?
The discovery of this element, in addition to Nihonium, Moscovium, and Tennessine, completed period 7 of the periodic table.
What is Oganesson?
Having 7 outer-ring electrons, the element krypton belongs to this periodic group.
What is group 17?
This Group 18 element has 2 outer-shell electrons, while the other common noble gases have 8.
What is helium (He)?
Since metallic character decreases from left to right, and and increases from top to bottom, this man-made element is known to have the highest metallic character of all the elements on the periodic table:
What is francium?
