Physical Science: Formation of Heavier Elements

Elements are made up of sub-atomic particles called protons, neutrons and electrons.

• True

• False

The identity of an element depends on how many neutrons it has.

• True

• False

Iron is one of the elements formed during the big bang nucleosynthesis.

• True

• False

Nucleosynthesis combines nucleons(protons & neutrons) to form elements.

• True

• False

The Big Bang is an explosion.

• True

• False

The Universe was colder 13.8 Billions years ago.

• True

• False

The higher the energy of the particles in an objects are, the higher the temperature of that object will be.

• True

• False

Mass can be converted into energy.

• True

• False

The temperature of the universe reached the point where the protons and neutrons could combine when they collided and formed new elements, this process is called
