Which changes occur as a cadmium atom, Cd, becomes a cadmium ion, Cd2+?

Chemistry
1 answer:
koban [17]3 years ago

The answer is (3). To form the cation (positive ion), Cd must lose negative charge, so two electrons are lost. This loss in electrons also increases the effective nuclear charge/ reduces electron shielding. In other words, with two less electrons to hold, the nucleus exerts a stronger attractive force on the remaining electrons, so the electron cloud is pulled closer to the nucleus. The radius therefore decreases.

Mashutka [201]

C.. it wants to try to remain in a state of equilibrium or equal

with that being said it wants to electrons to be equal to the number of electrons as much as possible

its like static friction when you rub a balloon on your head... you are replacing electrons for neutrons and that why it can stick to a wall after you rub it on your head because a wall only has negative atoms and when you rub the balloon on your head it takes some positive and charges it up positively and attracts to the negative atoms on the wall

_____ is a gel-like substance enclosed by the cell membrane that contains the cell's organelles. A) chloroplast B) cytoplasm C)
stepan [7]

Answer: The correct answer for the blank is-

B) cytoplasm.

Cytoplasm is the fluid filled compartment ( a thick, gel like substance) within the cell of a living organism that is mainly composed of water, salts, and proteins. It is surrounded by the cell membrane ( plasma membrane) and contains all the parts of cell ( such as in eukaryotic cell, it contains all the cell organelles except nucleus). It is the site for all the essential cellular processes.

Thus, option B) is the right answer.
