What are the elements in groups 1A to 8A called?
The elements in group 1a to 8a called representative elements. This is due to the fact that they portray as wide array of chemical and physical properties.
Why are the elements in groups 1A-8A called the representative elements?
They follow a pattern for valence electrons.
How many elements have electrons at ns2np6?
All of the elements in group 8A have this electron configuration except for He! (So a total of 5 elements)
What are group 8A elements called?
I - Alkali Metals II - Earth Alkali Metals III - Boron Group IV - Carbon Group V - Nitrogen Group VI - Chalcogenes VII - Halogenes VIII - Noble Gases
Why are members of group 18 unreactive?
The goal of every element is to complete its outer shell of electrons through reacting with other elements. And atom's outer shell can hold up to eight electrons. The elements of group 8 already have 8 electrons, so they have no reason to react with other elements. Because they don't react they're called noble gasses.
What are the elements in groups 1A to 8A called?
The elements in group 1a to 8a called representative elements. This is due to the fact that they portray as wide array of chemical and physical properties.
Does a group of elements share the same number of valence electrons?
Yes In Groups 1A through 8A
Why are the elements in groups 1A-8A called the representative elements?
They follow a pattern for valence electrons.
What elements are very stable and have low reactivity?
They are called noble gases or inert elements. Belong to group 8A or 18 They are called noble gases or inert elements. Belong to group 8A or 18 They are called noble gases or inert elements. Belong to group 8A or 18
What are the characteristics of its group in 1a-8a?
I love you LUKE A.
Which group of elements are called the noble or inert gasses?
Group 8a
What are the 4 main categories of elements found on the periodic table?
- The Group 1A elements are called alkali metals. - The Group 2A elements are called alkaline earth metals. - The nonmetals of Group 7A are called halogens. - The Group 8A elements are called the Noble Gases
What group does the alkaline earth metals belong to?
The alkaline earth metals belong to group 2A elements. The alkali metals belong to group 1A elements. The halogens belong to group 7A elements. The noble gases belong to group 8A elements.
Which group of elements are stable?
the most stable element group is the noble gases group
When a neutral atom such a potassium loses 1 electron its charge becomes what number?
Potassium's charge becomes 1+ since it is Group 1A on the periodic table. The elements in that group all like to lose 1 electron to become more like the noble gases in Group 8A.
What group of elements in the periodic table are most likely to be in the gaseous form?
Noble Gases, Group 8A
What lines can be broken down tables into groups on periodic table?
groups 1a,2a,3a,4a,5a,6a,7a,8a : elements of each group generally have similar properties do to similar #s of valence e-s.
