Answer:

Explanation:

Ionic bonds are also known as electrovalent bonds.

For ionic bonds to form, there is transfer of valence electrons from the metal to the non-metal. Metals are electropositive and would easily allow electrons to leave.

The goal of bonding is to achieve the octet configuration. An atom can lose or gain electrons to achieve this.

For example, to form NaCl, Na would loose its 1 valence electron. Cl would gain the Valence electron and complete it's octet with it.

This transfer of electron creates the ionic bond.

The metal which is less electronegative becomes positively charged. The non metal being more electronegative would become negatively charged.

Ionic compounds are polar compounds.

Imagine tying a string to a ball and twirling it around you. How is this similar to the moon orbiting the Earth? In this example

Tema [17]

Its similar to the moon orbiting the earth because lets say that the sing is moon and the ball is earth has the "moon" orbits around the "earth" the string ends up tying around the ball till its no more

i think i hope this example helps you somehow srry that i dont know more then that :/

(a) When we rub a plastic rod witha piece of fur, --------------transfer from ----------------to the ------------. In the result

Answer:

Explanation:

When the two dissimilar bodies rubbed together, they the both of the bodies becomes charged. One of the body gets positive charge and the other body gets negative charge.

the positively charged body loses some electrons and the negatively charged body gains some electrons.

According to the properties of charge when the plastic rod is rubbed with the fur, the plastic rod has a tendency to get the negative charge and the fur has a tendency to get positive charge.

So,

When we rub a plastic rod with a piece of fur, electrons--------------transfer from fur----------------to the -------plastic-----. In the result charging fur with -positive-----------charge and plastic rod with-----negative--------charge.
