Describe and explain the trend in atomic a.radius within the group.Explain the difference between the size of b.the atoms and th

e size of the ions.

disa [49]2 years ago

Answer:

A. The atomic radius increases (in a group) with the increasing atomic number. This is because atomic size generally increases from top to bottom within a group because the greater the number of protons means the greater amount of electrons. The amount of electrons in orbitals determine an atom's size/radius.

B. Since Group 1A (Alkali Metals) are metals, they tend to form cations. Cations are always smaller than their original atom because the greater positive charge from the nucleus closes in the space between it and the electrons, thus "shrinking" its size. This is why the ionic radii are smaller than the atomic radii of the same element.

Which wind blows cool air toward the sea at night ?
alexira [117]

Answer:

Land breeze is the wind that blows cool air from land towards sea at night.

Explanation:

Land breeze is a type of wind which is cool and blows towards sea. It occurs due to the difference in the temperature of water and land. At night, the lands cool quickly due to the removal of heat from it. So the air that is present on land is cool down and this air moves towards sea. So this breez is called land breeze because it moves from land.

Using two different instruments I measured the length of my foot to be 27 centimeters and 27.00 centimeters. Explain the differe
Sophie [7]

Answer:

As you used two diferent instruments, one is more sensitive than the other.

Explanation:

The sensitivity of an instrument is the minimum amount of magnitude that can be  differentiate a measurement system.

In method A, you got 27 cm, so if in method B, you got 27.00, method B is more sensitive. It's like saying that one system measures more than the other

AleksAgata [21]
Although the moon's distance from earth varies each month because of its eccentric orbit, the moon's mean distance from Earth is nonetheless increasing at the rate of about 3.8 centimeters (1.5 inches) per year

Which type of carbon fixation stores carbon dioxide in acid form? a. c3 b. c4 c. cam d. all of the above
Luba_88 [7]

The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.

<h3>What are CAM?</h3>

CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.

In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.

Hence option (C) is correct.
