Why does the ionization energy tend to decrease from top to bottom within a group?
there is an increase in atomic number and atomic size down the group due to addition of extra shells.this increase in the atomic size overcomes the effect of an increase in the nuclear charge.Therefore ionisation energy decreases with an increase in atomic size i.e.,it decreases as one moves down a group..
If the concentration of the dye was decreased would the distance it moves increase?
If the concentration of the dye is decreased, the distance it moves may increase because there will be less dye molecules competing for space and the movement may be less restricted. However, other factors such as the solvent properties and conditions of the experiment can also influence the dye movement.
How is the reactivity of metals related to the periodic table?
In the alkali metals column (Group 1), atomic radius increases down the group and reactivity increases. There are more shells preventing the attraction between the positive nucleus and negatively charged outer electron. (All Group 1 elements have 1 electron in their outer shell). Also, because they contain more shells down the group, the distance between the nucleus and electrons is increased. Therefore the electrostatic force is lessened between them. Both of these allow the outer electron to be lost easier to other elements, thus increasing reactivity.
Why is there a sudden jump in the atomic radius in elements in group 18 and the next higher element in the next period in group 1?
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
What happens if a piston is used to decrease the volume of a contained gas?
If a piston is used to decrease the volume of a contained gas, the pressure of the gas will increase, following Boyle's Law. This is because as the volume decreases, the gas particles become more confined and collide with the container walls more frequently, resulting in an increase in pressure.
Does the resolution increase or decrease as one moves to the higher magnificaions with the micorscope?
Increases
Does working distance increase or decrease as one moves to higher magnification?
decreases
When an object falls freely the kinetic energy of the object will?
It will decrease if the object moves upward; decrease if the object moves downward.
As energy moves up the food chain does it increase or decrease?
It decreases by 90% and only 10% goes on
Does the depth of field increase or decrease when one moves to a higher magnification on a microscope?
The depth of field decreases.

Will salinity increase or decrease with depth at high latitudes?
No, because the heavy precipitation of the tropical region causes the surface salinity to decrease. The salt moves to the bottom. Remember that rainwater is fresh.
Write a general statement that describes the periodic trend in the solubility of alkaline earth metal compounds?
The solubility of alkaline earth metal compounds generally increases down the group in the periodic table. This trend is particularly evident for hydroxides and sulfates, where the solubility of hydroxides increases from beryllium to barium, while sulfates show a decrease in solubility from magnesium to barium. The increase in ionic size and decrease in lattice energy as one moves down the group contribute to this trend. Overall, this results in greater solubility for heavier alkaline earth metals compared to their lighter counterparts.
A force that acts on an object does only when the object moves?
A force will produce acceleration when the object moves. force in the line of motion will increase the acceleration and the force opposite to the line of motion will decrease the acceleration.
Does air lose heat as it moves faster?
Yes it does the gas law that applies here says increase in velocity = decrease in temperature and pressure.
Moves characters to the right of insertion point?
Space,Tab or on home tab in paragraph section choose increase or decrease indent
What does the diaphragm do when exhaling?
When exhaling, the diaphragm relaxes and moves upwards, causing a decrease in the volume of the chest cavity. This increase in pressure pushes air out of the lungs.
