The outer electron configuration of an alkali metal has?
1 electron in the s orbital
Why do all group 1 elements have 1 electron on the outer shell?
Yes, all alkali metals do so.
A chemical family of elements contains elements with?
Elements in the same family (or group) have the same amount of electrons in their outer shell. For Example, all elements in Group 1 have 1 electron in their outer shells.
Which element has the noble gas configuration NE's?
Sodium has the configuration Ne 3s2 . Sodium is group-1 element.
The group that has one electron in its outer level?
Alkali Metals (Group 1)
What is the outer electron configuration for all group 1 elements?
1
What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
Why are the properties of the elements in a group are usually similar?
Take the alkali earth metals as an example, column I in the Periodic Table. All of them have an unpaired s electron in their outer shell. All of them will form a +1 cation. When you go down the column, all of them will have a similar outer shell configuration. The transition metals are different, however.
What are the group configuration notation for each d block group?
group 3- (n-1)d1 ns2. Group 12 (n-1)d10 ns2, groups 4-11 do not necessarily have identical outer electron configurations. Where n represents your period that you are in.
The outer electron configuration of an alkali metal has?
1 electron in the s orbital
Why do all group 1 elements have 1 electron on the outer shell?
Yes, all alkali metals do so.
What achieve noble gas configuration by losing one electron?
All elements from group 1
What charge does the alkali metals always form cations with?
+!. The lakali metals are Li, Na K etc in group 1 with an electronic configuration with just ns1 as the outer shell.
A chemical family of elements contains elements with?
Elements in the same family (or group) have the same amount of electrons in their outer shell. For Example, all elements in Group 1 have 1 electron in their outer shells.
Why do the elements in the group 1 and 2 react with group 17?
Elements in group 1 have 1 electron in their outer shell. Group 7 electrons have 7 electrons in their outer shell. This means that the group 1 element needs to give its electron to the group 7 element so that they both have full outer shells, making them stable. By a school boy in yr. 10
What do all Group 1 elements have?
One electron in their valence shell (outer most shell)
The number of electrons in the outer energy level of Group 17 elements is?
there are 7 electrons in the outer energy level of group 17 elements
