What are some properties of group 17 on the periodic table?
Group 17 (the halogens) are all highly reactive non-metals.
To what does the term periodic in periodic table refer?
The term "periodic" in the periodic table refers to the repeating patterns of chemical and physical properties of elements that occur across each period (row) in the table. This periodicity is based on the number of electrons in the outer energy level of the elements.
What is a group on a periodic table?
A vertical column on the Periodic table on the periodic table is called group. There are 18 groups on the table. These groups are also referred to as families. Each element in a group has the same number of valence electrons and, therefore, similar chemical properties (there are some exceptions though).
What are some important questions to ask about the periodic table?
Some important questions to ask about the periodic table include: What is the organization of elements based on? How are elements grouped together? What are the properties of elements in the same group or period? How does the periodic table help predict the behavior of elements?
What is meant by the Periodic Table?
A table in which properties of elements are repeated after some interval.
Why is hydrogen not included in group 1 in modern periodic table?
Even though hydrogen has a vacant electron in its outer shell, like many of the elements in group 1 of the periodic table, it has unusual properties, e.g. it is a gas at room temperature, whereas the other elements are all solid. As a result, some forms of the periodic table show hydrogen above the rest in the table, in its own special place. However, it is still in group 1
Why is silicon located and colored the way it is on the periodic table?
Silicon is a metalloid element, located in Group 14 of the periodic table. It is typically displayed as a light grey color on the periodic table due to its metallic properties combined with some non-metallic characteristics. Its placement in Group 14 reflects its intermediate properties between metals and non-metals.
What group of the periodic table would the atom be found?
An atom can be found in a specific group on the periodic table based on its number of valence electrons. The group number indicates the number of valence electrons an atom has, which in turn determines its chemical properties and reactivity.
What do boron silicon and arsenic have in common Use the partial Periodic Table for reference?
Boron, silicon, and arsenic are all members of Group 15 of the periodic table, also known as the nitrogen group. They are nonmetals (boron is a metalloid) with varying properties. Boron is the first element in the group, silicon is a metalloid with semiconducting properties, and arsenic is a metalloid with some similarities to a metal.
Is hydrogen in its own group?
Yes, it has some unique properties that set it apart from other nonmetals.
What elements are similar to iron?
What elements are similar to iron in a chemical property on the Periodic Table
How do one recognize a periodic trend on the periodic table?
Studying physical and chemical properties of chemical elements it is possible to recognize some trends in the periodic table.
