D)Cation is the answer. A cation is a positive ion fromed by the removal of electrons from the outermost shell of an atom.
Let's take Na ( Sodium ) whose At. No is 11 as an example.
When we arrange them in electronic configuration Sodium has 3 shells. 2 in its innermost shell (K), 8 electrons in its 2nd shell which is named as 'L' & lastly 1 electron in its outermost shell (M).
We know that in an atom the no. of protons, neutrons and electrons are equal.
In case of sodium, when only electrons are reduced while protons remained same. Previously, the No. of protons and electrons were equal. But this time, There is an extra proton(+). This is the reason when an electron is removed we get a cation.
There are two factors that causes atoms to loose electrons -
1) Atomic Size
2) Nuclear Charge
Answer:
233 g.
Explanation:
The solubility of silver nitrate at 20.0°C is 222 g per 100 g of water.
The solubility of silver nitrate at 50.0°C is 455 g per 100 g of water.
<em>∴ We need to add (455 g - 222 g = 233 g) of AgNO₃ to obtain a saturated solution at 50.0°C.</em>

Answer:
The answer is D) Electrolytic cell
Explanation:
An electrolytic cell is a device used for the decomposition by the electrical current of ionized substances called electrolytes.
When the two electrodes are connected by a wire, electrical energy is produced, and a flow of electrons takes place from the electrode.
These cells are the closest thing to a galvanic battery.
The answer to your question is ‘B
