Answer:
A positive ions is always smaller than the corresponding atom.
A negative ion is always larger than the corresponding atom.
Explanation:
The reason for this is that, when a positive ion is formed, a full shell is usually removed with its electrons thereby reducing the size of the electron cloud and decreasing the size of the electron cloud.
A negative ion is formed by addition of more electrons to the electron cloud hence it spreads out. Interelectronic repulsion accounts for the larger size of the negative ion.
2:2 is the answer to your question
Answer:
25th electron
Explanation:
the last electron is the valence electron. Assuming it has equal numbers of protons and electrons, then the 25th electron is the valence.

A toy car has a 1.5-A current, and its resistance is 2 . How much voltage does the car require?
V
Explanation:
Answer:
Seafloor spreading and other tectonic activity processes are the result of mantle convection. ... Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
