Choose the right answer: Atoms ...
are the basic blocks of matter
can be seen with our eyesight
are only found in atomic materials
aren't components of matter
Atoms are made of
neutrons, carbon and electrons
neutrons, protons and electrons
neutrons, oxygen and electrons
massive particles
Electrons
form part of the atom's nucleus
are positively charged
cannot move between atoms
are negatively charged, are outside the atom's nucleus and can move between atoms
When an atom loses an electron
it becomes positively charged
it becomes negatively charged
it stays neutral
Electricity is the movement or flow of electrons between atoms
true
false
Electrons can move in all materials
true
false

a defibrillator
An insulator is
a material in which electrons cannot move easily
a material that allows electrons to flow
a battery
an electrical circuit
The electricity we need to power things
is an electrical current that flows through conductors in closed circuits
flows in open circuits
does not need circuits to flow
is also called static electricity
The components of electric circuits are
power source, conductor, switch and insulator
power source, conductor, load and switch
insulator, copper and batteries
