Protrons, neutrons ,isotopes, oh my.....

I dont really get this, could you help me? thank you :)



1: How are protons and neutrons alike, and how are they different?





2: which of the subatomic particles is the smallest?






3: what are isotopes?

1. They have the same mass. But protons are positively charged and neutrons have no charge.

2. Electrons

3. They are atoms which have the same number of protons, but different number of neutrons.

:)

1. protons are postively charged. neutrons are neutral. you can get a proton and electron by splitting a neutron

2. electrons

3. isotopes are atoms of the same element with different number of neutrons. isotopes are considered atoms from the same element because they've the same proton number.

Smallest subatomic part. are electrons....protons and neutrons are in the necleus....isotope are element with diff. number of neutrons
