What is the name of family 18?
noble gases
Other groups with specific names are the pnictogens (group 15), chalcogens (group 16), halogens (group 17), and the noble gases (group 18, also known as inert gases). The groups can also be referred to by the first element of the group: For example, the chalcogens can be called the oxygen group or oxygen family.
What is the name of Group 18 or Viiia?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
Which of the following belongs to group 18?
Answer: (C)Ar i.e. Argon is a Noble gas. And all the noble gases falls under group 18. Other Noble gases are:- Helium, Neon, Krypton, Xenon, Radon and Organesson.
Why is group 18 on the periodic table called noble gases?
The group 18 elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are non-reactive and are called noble gases as they have their outermost orbit complete. Due to stable electronic configuration they hardly react with other elements.
Are there 8 or 18 groups in periodic table?
Groups are numbered from 1 to 18. From left to right in the periodic table, there are two groups (1 and 2) of elements in the s-block, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block.
Are there 18 periods and 7 groups?
There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons. A group is a vertical column of the periodic table, based on the organization of the outer shell electrons. There are a total of 18 groups.
Who is modern periodic table?
Mendeleev’s Periodic Table. Mendeleev, who first published his periodic table in 1869 (Figure 3.2. 1), is usually credited with the origin of the modern periodic table.
What element belongs in group 18 Period 6?
These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
Why are group 18 elements called that?
Which is a property of the gases in group 18?
The noble gases are a group of chemical elements that make up Group 18 on the periodic table. These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity.
Why there are only 18 groups in the periodic table?
Anyway, the community has pretty much settled on using 18 groups nowadays. The idea behind the periodic system is to find regularities (hence the name) between elements. It turns out, that individual groups and trends within them are similar in the 8 “main” groups (as you have learned).
What are the members of Group 18 called?
Members of group 18 in the modern periodic table are known as the noble gases.
What is the name for Group 18 in the periodic table?

What’s the difference between Group 8 and group 16?
For example, group 16 is variously described as the “oxygen group” and as the ” chalcogens “. However, iron group usually does not mean “group 8”. In chemistry it may mean either iron, cobalt, and nickel, or some other set of elements with similar chemical properties. In astrophysics and nuclear physics,…
How many valence electrons does group 18 have?
Members of group 18 have eight valence electrons, i.e., they have eight electrons in their outermost orbit (except helium). Thus, they exhibit a stable octet configuration.
