How substances are formed

Question 1

The particle model was made to help us understand matter

Question 2

Particle

Answer 2

a tiny bit of matter

Question 3

Particles are described as

Answer 3

1.tiny
2.impenetrable(impossible to pass through)
3.spheres
4.that are not visible to the naked eye

Question 4

metallic substances

Answer 4

A metallic bond is not solely restricted between 2 metallic atoms

Therefore, other metallic atoms can approach these 3 metallic atoms and form a bond with them

a collection of metallic atoms(that are all the same) is called a substance

Question 5

Ionic substances

Answer 5

A ionic bond is not solely restricted between 2 oppositely charged ions

Therefore, other oppositely charged ions can approach these 2 oppositely charged ions and form ionic bonds with them

a collection of ionic bonds(that are all the same) is called an ionic substance

Question 6

Molecule:

Answer 6

groups of atoms chemically bonded together

small/simple molecules are made up of a small number of non-metallic atoms covalently bonded together

Question 7

Covalent Bonds:

Answer 7

A covalent bond is solely restricted between 2 non metal atoms

other non-metallic atoms can approach these 2 non-metallic atoms but CANNOT form additional covalent bonds with them

a collection of (small) molecules (that are all the same) is called a (simple) molecular substance
