what is the reason for ionization energy across a period
Electronegativity increases across a period (left to right).
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
It is a trend in itself, it isn't caused by a trend.
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.
if you mean metals ..... for the same valence the radius decreases across a period and increases down a family
Electronegativity increases across a period (left to right).
across a period, the atomic size decreases as the effective nuclear charge increases.
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
increases from left to right across a period.
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
increases from left to right across a period.
Yes, as you move from left to right across the period.
It is a trend in itself, it isn't caused by a trend.
Electronegativity increases across a period. Element becomes more negatively charged.
going down a group, electronegativity decreases going across a period, electronegativity increases
The trend of boiling points across a period in the periodic table should decrease from metals to nonmetals. The trend becomes more complicated between metals, the boiling point of metals tends to increase across a period.
