Atomic Structure and Periodic Table

Which particle has a positive charge?

• electron
• orbital
• proton
• neutron

Choose the particle that has no charge.

• nucleus
• neutron
• proton
• electron

This causes the mass of the nucleus to increase.

• adding an electron
• adding a neutron
• more orbitals
• adding negatively charged particles

An electron has a _____ charge.

• negative
• positive
• neutral

What are valence electrons?

• electrons on the first orbital always
• nucleus
• the outermost shell
• the number of electrons on the outermost orbital

Which particles make up the nucleus of an atom?

• protons and neutrons
• electrons and protons
• electrons, protons, and neutrons
• electrons and neutrons

The subatomic particle that determines the identity of an element.

• neutron
• proton
• electron
• outer shell

What charge does the nucleus have and why?

• positive - the neutrons do not have a charge
• positive - the neutrons and protons are positively charged particles
• neutral - the neutral charge dominates the positive charge
• neutral - electrons cancel out the positive charge of the atom
