flourine has lesser number of electrons ( 2) than chlorine ( 3)

# data[].attributes.body
Why does fluorine have more non-metallic property compared to chlorine?

They in different period group

# data[].attributes.body
cause yes and fluorine is in a period before chlorine

# data[].attributes.body
This is because Li has a lower electronegativity and smaller atomic radius than Na.

# data[].attributes.body
the number of electron shells in the element

# data[].attributes.body
elctron

# data[].attributes.body
It has less electrons

# data[].attributes.body
more electron shells

# data[].attributes.body
There are more electrons in sodium

# data[].attributes.body
Different groups

# data[].attributes.body
it is what it is

bcuz fluorine got lesser electrons than chlorine

# data[].attributes.body
lesser electrons

# data[].attributes.body
group number is different

# data[].attributes.body
number of valence electrons

# data[].attributes.body
Metallic character increases as we move from top to bottom in a group as atomic size increases so sodium is more metallic

# data[].attributes.body
number of electron shellss

# data[].attributes.body
lesser electrons

# data[].attributes.body
more electrons

# data[].attributes.body
there are less electrons

# data[].attributes.body
as there are more electrons???

# data[].attributes.body
bcuz sodium got more valence electrons than lithium

# data[].attributes.body
number of electron shells
