To which group do Alkali metals belong to and why are there grouped here?
Group 1. They have only one electron in their outer shell.
What are the elements of Group 18 usually called?
The noble gases
Matter cannot be created or destroyed in a chemical reaction

Describe the structure of atoms by telling where are each of its particles located.
Protons and neutrons are found at the center in an area called the nucleus.
Electrons move around the nucleus in the orbits or shells.
Tell three characteristics shared by alkali metals.

Why are the noble gases so stable?
Their outer shell is full.
Tell the reactants and products for combustion reactions.
Reactants: fuel and oxygen
Products: carbon dioxide and water

How many protons, neutrons and electrons does the element argon have? (consult a periodic table)
Atomic number: 18; Mass number: 40
Argon: 18 electrons; 18 protons; 22 neutrons
To which group do the halogens belong to and why?
Group 17, their outer shell presents 7 electrons.
What is the name of the scientist who designed the periodic table?

Synthesis vs Decomposition reaction
Synthesis - multiple smaller reactants make one larger product (A + B = AB)
Decomposition - a large reactant breaks into several smaller products (AB = A + B)
