The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

A hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:

kupik [55]

hydrogen-like ion is an ion containing only one electron. The energy of the electron in a hydrogen-like ion is given by:

En = −(2.18 × 10^−18J) Z^2 ( 1/n^2 )

where n is the principal quantum number and Z is the atomic number of the element. Plasma is a state of matter consisting of positive gaseous ions and electrons. In the plasma state, a mercury atom could be stripped of its 80 electrons and therefore could exist as Hg80+. Use the equation above to calculate the energy required for the last ionization step.hydrogen-like ion is an ion containing only one electron.

In an ionic bond:

Fynjy0 [20]

In an ionic bond :

=》B. one atom accepts electrons from another.

in this bond an atom ( metallic ) loses its electrons and another atom ( non- metallic ) accepts the electrons, and since there isn't the equal positive and negative charges in the atoms, they forms cations ( +ve charge ) and anions ( -ve charge )

and get stacked or attracted to each other by strong electrostatic force.
