Question

match the phrase with the subatomic particle being described. drag & drop the answer what is the positively - charged particle of an atom? what is the neutrally - charged particle of an atom? what is the negatively - charged particle of an atom? the atomic # = the number of ____ atomic mass (rounded) - the atomic number = can be given away or obtain more to create an ion. located on shells around the nucleus of the element. is equal to the number of protons. if this particle varies in abundance it will create an isotope. can never be changed in an element.

Explanation:

1. Protons are positively - charged subatomic particles in an atom's nucleus.
2. Neutrons are neutrally - charged subatomic particles in the nucleus.
3. Electrons are negatively - charged subatomic particles that orbit the nucleus in shells. The atomic number is equal to the number of protons. Atomic mass (rounded) minus the atomic number gives the number of neutrons. Electrons can be gained or lost to form ions. In a neutral atom, the number of electrons is equal to the number of protons. Variation in neutron abundance creates isotopes. The number of protons in an element is fixed.

Answer:

What is the positively - charged particle of an atom? - Proton(s)
What is the neutrally - charged particle of an atom? - Neutron(s)
What is the negatively - charged particle of an atom? - Electron(s)
The atomic # = the number of Protons
atomic mass (rounded) - the atomic number = Number of Neutrons
Can be given away or obtain more to create an ion. - Electron(s)
Located on shells around the nucleus of the element. - Electron(s)
Is equal to the number of protons. - Number of Electrons (in a neutral atom)
If this particle varies in abundance it will create an isotope. - Neutron(s)
Can never be changed in an element. - Proton(s)
