Answer:
Ionic bond
Explanation:
Ionic bonding:-
This type of bonding is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.
Thus, the atom which loses the electron which is gained by the another, there is a electrostatic attraction between two which which results in the formation of ionic bond.
For example:-
Calcium is the element of second group and forth period. The electronic configuration of Calcium is - 2, 8, 8, 2 or
There are 2 valence electrons of Calcium.
Sulfur is the element of sixteenth group and third period. The electronic configuration of sulfur is - 2, 8, 6 or
There are 6 valence electrons of sulfur.
Thus, calcium loses two electrons to sulfur and sulfur accepts these electrons to form ionic bond.
Calcium sulfide, is formed when 2 valence electrons of calcium are loosed and they are gained by sulfur atom.
Earth orbits the sun 100,000 times closer than the Oort Cloud, at an average of 92,955,807 miles (149,597,870 km) or 0.000015898 light years. The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system.
