What causes the sheilding effect to remain constant across a period?

Electron shielding is not a factor across a period because they all have the same number of electron shells! No further (extra) shells means that they are all affected by electron shielding equally.

What trend does electronegativity follow?
In electronegativity, the first ionization energy increases as it moves from left to right across a period . The nuclear charge also increases and the shielding effect is constant when moving across.
Why does bigger size atom have more shielding effect?
The bigger the atom, the larger the number of electrons between the outermost energy level and the positively charged nucleus. As a result, the attraction between the electrons in the outermost energy level and the nucleus are slightly weaker, and so, the larger the atom, the greater the sheilding effect.
Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?
No.
Does a chemical change effect mass?
Mass is a constant Quantity according to Newtonian Physics.
How does chloroform effect the biological function of the body?
It causes unconsciousness and even death.
Why does the bigger size atoms have more sheilding effect?
The number of electron shells is higher.
Why anthroprogenic ozone does not provide us sheilding effect?
It does, but there just isn't enough of it (density, or height) to provide any significant increase in protection.
What is the effect of varying the temperature on the volume of a constant mass of a gas at a constant pressure?
the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
Which of these causes global winds to appear to turn instead of blow straight across the earths surface?
Coriolis effect
What is the consequeces of sheilding effect?
The shielding effect in chemistry refers to inner electrons shielding outer electrons from the attraction of the nucleus in an atom. This results in a decrease in the effective nuclear charge felt by the outer electrons, leading to changes in atomic and chemical properties such as ionization energy and atomic size in elements across a period.
Reducing the current you a circuit causes what?
Reducing the current to a circuit causes a higher resistance -- assuming constant Volts. Also, reducing the current to a circuit causes lower Volts -- assuming constant resistance.AnswerAltering the current has absolutely no effect on a circuit's resistance. Reducing the current will reduce line losses (I2R) and reduce the voltage drop along a conductor.
What is the uncertainty of a constant value?
It is the accuracy in the estimate of the constant or the effect of rounding.
Which of these causes global winds to appear to turn instead of blow straight across the earth's surface?
The Coriolis effect is when global winds appear to turn instead of blowing straight across the earth's surface.
Can you give a sentence using the word constant?
The passage of time has a constant erosive effect.
How a dynamo woks?
Dynamo has constant magnet inside.When movement comes up ,magnet starts turning .And outside of magnet has coiled wire .So this movement of magnet causes electromagnetic effect .Finally current consists with this electomagnetic effect.
What trend does electronegativity follow?
In electronegativity, the first ionization energy increases as it moves from left to right across a period . The nuclear charge also increases and the shielding effect is constant when moving across.
What is a primary effect?
it is a blast effect causes damage
