How can the periodic table be used to look at relative electronegativity of elements?
Fluorine is the most electronegative element. Down any group, electronegativity increases and across a period (from left to right), electronegativity increases.
Electronegativity increases as the size of the atom increases. True False?
Now there's an interesting question. In general, electronegativity increases as one progresses down a period, while electronegativity decreases as one moves down the group. The most electronegative element is fluorine, while the least electronegative nonradioactive element is francium.
How does the numbers of electrons change across a period of elements?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How do the metallic properties of the elements change as you move from left to right on the periodic table?
Metallic character decreases as we move across a period. The electronegative character increases as we move across a period. So the element across the period will be non mettalic in nature.
What general trend in electronegativity do you note going down a group across a period?
going down a group, electronegativity decreases going across a period, electronegativity increases

Does electronegativity increases or decreases as you move left to right across a period on the periodic table?
Electronegativity generally increases as you move left to right across a period on the periodic table. This is because the effective nuclear charge increases, pulling electrons closer to the nucleus and making it easier for the atom to attract electrons.

What is the trend in the electronegative of the elements from-left to right and from top to bottom?
Electronegativity generally increases from left to right across a period and decreases from top to bottom down a group. This is because as you move across a period, the nuclear charge increases, attracting electrons more strongly. Down a group, the atomic size increases which leads to a decrease in electronegativity.
What is the general trend of the melting points of elements on the periodic table?
The general trend of melting points of elements on the periodic table increases from left to right across a period and decreases down a group.
How does the number of valence electrons for element change across a period?
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
How does electonegativity relate to the periodic table?
Electronegativity decreases down a group and increases across a period. So the most electronegative element is at the top right, fluorine (the noble gases don't count) The least electrnegative element is bottom left, francium.
How do the metallic properties of the elements change as you move from left to right on the periodic table?
Metallic character decreases as we move across a period. The electronegative character increases as we move across a period. So the element across the period will be non mettalic in nature.
What are the general prorperties of the elemnts in the group to the right in the modern periodic table?
Non metals are present to the right side. They possess electronegative character.
