F = #9, 9 electrons 1s2, 2s2, 2p5
Cl = #17 , 17 electrons 1s2, 2s2, 2p6, 3s2, 3p5
Notice both end in s2, p5. That is why they have similar properties.
Both only need 1 electron to complete the octet ( s2 p6 in the outer shell, very stable)

The elements Li and F combine to form an ionic compound The electron configurations in this compound are the same as the electron configurations of atoms in which group?
Group 18
Which elements have electron configurations that end in ns 2 and np 5?
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
Which elements have electron configurations that end in ns 2 np 5?
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
What can be said about the electron configurations of all the elements in a group?
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
Identify the group of elements that corresponds to each of the following generalized electron configurations noble gasns2np5?
7A
Why elements are place in a group?
Elements with similar electron configurations are placed in the same group.

Which elements have electron configurations that end in ns 2 np 5?
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
What has electron configurations of noble gases by gaining one electron?
All halogens or group 17 elements.
Identify the group of elements that corresponds to each of the following generalized electron configurations noble gasns2np5?

What can be said about the electron configurations of all the elements in a group?
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
How do the electron configurations within?
The core of the configuration is the same for all elements in a group, the outer shell electrons are also arranged similarly.
Why do groups among the main-group element display similar chemical behavior?
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
The electron configurations of the noble gases from neon to radon in the periodic table make these elements part of the?
They are all members of the noble gas group (group 18).
What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
What groups have electron configurations that end with 1 electron in the P-Block?
group 13 or IIIA
