What trend in electronegativity do you see as you go down a group-family on the periodic table?
Electronegativity decrease down in a group.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
What happens to the electronegative as you go across the periodic table?
As you across the Periodic Table from left to right, electronegativity will increase. As you go down a group of the periodic table, electronegativity will decrease. As electronegativty is a particular element's electron attraction, this trend does not apply to noble gases, since they already have a full valence shell of electrons. The simplest way to remember and apply this is just to know that fluorine is the most electronegative element, and then work your way from there. Ex: Since sulfur is closer to fluorine than aluminum, sulfur is more electronegative.
How is electronegativity related to atomis size?
No. Electronegativity decreases as the size of the atom increase. As you go across a row in the periodic table, you will see that electronegativity increases and the size of the atom decreases. Similarly, as you go down a column you will notice that the size of the atom increases and electronegativity decreases.
Which arrangement of elements represents an increasing trend of electronegativity?
Electronegativity is the attraction of bonding electrons by an atom. As the size of the atom increases, so does the distance from the nucleus to any other atom's electrons. Electronegativity increases as you go right within a period or up within a group.
What happens to electronegativity as you go across a period?
The electronegativity increases
As you move across a period of a periodic table from left to right what happens to the elements electronegativity?
it decreases
What trend electronegativity do you see across period on the periodic table?
The trend as you move from left to right across a period in the periodic table, the electronegativity increases due to the stronger attraction that the atoms obtain as the nuclear charge increases. Moving down a group, the electronegativity decreases due to the longer distance between the nucleus and the valence electron shell, thereby decreasing the attraction, making the atom have less of an attraction for electrons or protons.
What trend in electronegativity do you see as you go down a group-family on the periodic table?
Electronegativity decrease down in a group.
How does electronegative change going down and across the periodic table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
Describe the trends in electronegativity in the periodic table?
Electronegativity increases across a period , this is because the Atomic radius of elements decrease due to the nuclear charge increasing.Decending a group electronegativity decreases because atomic radius increases due to electrons moving into new main energy levels (spdf), so the most elecronegative element is fluorine Hope that helps ! xIf you didn't understand this, I am deeply sorry.
What is the trend in electronegativity and ionization energy as you go down a row or across a period?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
What happens to the atomic number as you go across a period?
The atomic number increases as one go across a period.
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
What is true about the properties of the elements in any one period of the Periodic Table?
All of the elements in any one period of the Periodic Table have the same number of valence electrons.
What changes as you go across a period?
