It can fit two more electrons within its valence shell to follow the octet rule. It will have a -2 charge to gain those two electrons to fill its octet.
In water particles a much closer together and they can quickly transmit the vibration energy from one particle to the next. This means the sound wave travels over four times faster than it would in air but a takes a lot of energy to start the vibration.
Hopefully This Helped You!

Answer:
Explanation:
Ground state electron configuration of potassium (K) is 1s2 2s2 2p6 3s2 3p6 4s1. The valency of the element is determined by electron configuration in the excited state. This electron configuration shows that the last shell of the potassium atom has an unpaired electron (4s1). So the valency of potassium is 1.
