Why does the trend in electronegativey of elements across a period increase from left to right?

It increases from left to right across a period because as electrons are added to the same energy level, and the closer an atom gets to having an octet of electrons, the easier it is for the atom to attract electrons from other atoms, either through ionic bonding or covalent bonding.

Has largerst ionization energy in its period?
Ionisation energies GENERALLY increase across a period. As a result, the noble elements (i.e. Group 0 elements) usually have the highest ionisation energies, as they are highly stable.
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.
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).
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What happens to the reactivity of elements in group a as atomic number increase across a period?
they do becaused they want to do it
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
Has largerst ionization energy in its period?
Ionisation energies GENERALLY increase across a period. As a result, the noble elements (i.e. Group 0 elements) usually have the highest ionisation energies, as they are highly stable.
How does metallic of the elements vary across a period?
Across a period, the metallic character decreases.
Elements of the same row across?
the period
Why does atomic size increase from left to right across a period?

Ionization energies tend to do what from left to right across a period?
increase from left to right across a period.
How does the number of valence electrons for elements 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 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).
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
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.
