Unit 2 - Structures and Bonding

Question 1

How are compounds formed?

Answer 1

When atoms of two or more elements are chemically combined together

Question 2

What is an isotope?

Answer 2

Isotopes are different atomic forms of the same element, which have the same number of protons but a different number of neutrons

Question 3

What is ionic bonding?

Answer 3

Ionic bonding is where an electron from one atom is transferred to another atom.

This creates 2 ions as one atom looses an electron and one gains one.

Question 4

What type of bond is an ionic bond?

Answer 4

An electrovalent bond

Question 5

What does ionic bonding happen between?

Answer 5

A METAL and a NON-METAL

Question 6

When do positive ions form?

Answer 6

When metal atoms **loose **electrons

Question 7

What does the number of electrons lost determine?

Answer 7

Rge number of positive charges on the ion

Question 8

What is a chemical bond?

Answer 8

Transferring or sharing electrons in the outermost shell

Question 9

What happens when an element gains a full outer shell?

Answer 9

It reaches noble gas configuration

Question 10

What type of lattice do ionic compounds have?

Answer 10

Giant ionic lattices

Question 11

What forces occur in giant ionic lattices?

Answer 11

Very stong electrostatic forces of attraction, between oppositely charged ions, in all directions
