What Are The Following Groups Known As I Group 1 II Group 17?

Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.



What is Group 16 on the periodic table called?

oxygen group element


Which group of the periodic table contains the most reactive metals?

alkali metals element


Which of the following is arranged according to increasing reactivity?

According to the increasing order of there reactivity, the given elements are arranged as Copper<Zinc<Aluminium<Magnesium<Sodium.


Why are group 17 elements highly reactive?

Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. This characteristic makes them more reactive than other non-metal groups.


How do group 1 and Group 17 elements differ from each other?

The elements of group 1 are metals whereas the elements of group 17 are non-metals. The number of valence electrons in group 1 is 1 and the number of valence electrons in the elements of group 17 is 7 . The elements of group 1 are electropositive whereas the elements of group 17 are electronegative.


What is the name of group 15?

nitrogen group element


What are the name of group 1 and group 17 elements?

For example, the elements of Group 1 are known as the alkali metals, Group 2 are the alkaline earth metals, Group 17 are the halogens, and Group 18 are the noble gases.


What is Group 18 in the periodic table called?

noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).


What is the only metalloid In Group 17?

Boron is also the only metalloid in this group. The other four elements in the group—aluminum (Al), gallium (Ga), indium (In), and thallium (Tl)—are all metals.


What are the following groups known as I group 1 II Group 17?

Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.


What is a severe winter storm?

A severe winter storm is defined as a prolonged event involving snow or ice. The characteristics of severe winter storms are determined by the amount and extent of snow or ice, air temperature, wind, and event duration (National Weather Service, 2009).


How is math done in China?

The Chinese Method, or stick method, of multiplication involves properly placing and crossing sticks. You simply lay out sticks consistent with the place values of the digits being multiplied. Then, you count the places where the sticks cross.


What do you do in a severe thunderstorm?

The best way to protect yourself and your family in case of a thunderstorm is to follow these steps:

What are the four types of winter severe weather?

Types of Winter Precipitation

  • Snow. Most precipitation that forms in wintertime clouds starts out as snow because the top layer of the storm is usually cold enough to create snowflakes.
  • Sleet. Sleet occurs when snowflakes only partially melt when they fall through a shallow layer of warm air.
  • Freezing Rain.
