Question

almost all of an atoms mass is found in its nucleus, located in the center of the atom. an atoms nucleus can contain two types of particles: protons and neutrons.
the nucleus of every atom contains one or more protons. each proton has a positive electrical charge.
in many atoms, the nucleus also contains neutrons. a neutron has no electrical charge.
match each property with the part of an atom it describes.
neutron proton nucleus
can contain two types of particles
is a particle present in all atoms
has no electrical charge

Explanation:

1. For "can contain two types of particles": From the text, "An atom’s nucleus can contain two types of particles: protons and neutrons", so this property matches "nucleus".
2. For "is a particle present in all atoms": The text says "The nucleus of every atom contains one or more protons", meaning protons are in all atoms, so this matches "proton".
3. For "has no electrical charge": The text states "A neutron has no electrical charge", so this matches "neutron".

Answer:

• can contain two types of particles: nucleus
• is a particle present in all atoms: proton
• has no electrical charge: neutron
