As we move down a family,although nuclear charge(proton number)increases,the number of shells increases.This make the outermost electrons far away from nucleus and electrons feel less attracted to the nucleus.SO electron negativity decreases.It is opposite to first ionization energy where it is easier to ionize electrons as we move down a family.On the contrary,it is difficult to attract electrons.
What else can I help you with?
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 table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
When matter loses its particles slow down?
When matter loses energy, its particles slow down. This decrease in kinetic energy leads to a decrease in particle movement and ultimately a decrease in temperature.
When will an atom be electronegative?
An electronegative atom gain electrons.
Does the first ionization energy increase or decrease from top to bottom for the noble gas family?
The first ionization energy decrease from top to bottom for the noble gas family.
What trend in electronegativity do you see as you go down a group-family on the periodic table?
Electronegativity decrease down in a group.
Why do electronegaativity decrease as you move down a group?
Most often yes, if you're unsure, look on the periodic table, the elements electronegativity is usually located labeled, i.e electronegativity of F (the most electronegative element) is 4.0
How does electronegative change going down and across the table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
Why the elements of group 14 are most electronegative elemenets?
There is no Group 14. The elements of the group 7A are the most electronegative. Basically, electronegativity is the ability to attract electrons. Group 7A elements, or halogens, need just one more electron to reach stability, and are very reactive. So, they can easily accept that electron. In other words, their ability to attract electrons is the highest.
Why are halides electronegative if they are cations?
Halides are typically anions, not cations. Anions tend to be electronegative because they have gained electrons to achieve a stable electron configuration. Cations, on the other hand, are positively charged and usually not considered electronegative.
What is the percentage decrease in 3 years 21000 down to 18000?
14.3% decrease.
When matter loses its particles slow down?
When matter loses energy, its particles slow down. This decrease in kinetic energy leads to a decrease in particle movement and ultimately a decrease in temperature.
When will an atom be electronegative?
An electronegative atom gain electrons.
Why years in BC decrease?
they decrease because it counts down until Jesus is born
Which is more electronegative Sr or Be?
Sulfur is more electronegative than beryllium.
What is a decrease in magnitude and velocity called?
A decrease in magnitude is typically referred to as a decrease in intensity or amplitude. A decrease in velocity is commonly described simply as slowing down.
Does the first ionization energy increase or decrease from top to bottom for the noble gas family?
The first ionization energy decrease from top to bottom for the noble gas family.
