Two atoms of different elements will definitely have different numbers_____

• Nuclei
• Protons
• Neutrons
• Electrons

An ion forms when an atom gains or loses

• Protons
• Neutrons
• Electrons

A neutral atom would become an ion that has a charge of 2+ by 

• Losing two protons
• Losing two neutrons
• Losing two electrons

An alpha particle consists of 

• Energy only
• 1 high-energy electron
• 1 proton and 1 electron
• 2 protons and 2 neutrons

Isotopes are atoms that have different

• Mass numbers
• Element names
• Atomic Numbers

Two atoms that have different numbers of protons are 

• Different ions
• Different isotopes
• Different elements

Two neutral atoms that have the same atomic number and different mass numbers are

• Ions
• Isotopes
• Alpha particles
• Different elements

An ion that has a negative charge is formed when an atom 

• Loses neutrons
• Loses electrons
• Gains neutrons
• Gains electrons

Define Atom

• It is the smallest piece of an element that still represents that element
• Is an element has the electrons in their electron cloud
• A positively charged isotope

How are Protons and Neutrons similar

• Both are in the nucleus of the atom and they both have the relative mass of 1
• They both have alpha particles and have the relative mass of 2
• They both have 1 high-energy electron and different elements
