Advanced Chem - Unit 2 Review Part 2: Atomic Structure

This particle determines what element you have - the elements identity.

• electron
• proton
• neutron
• valence shell

This causes the mass of the nucleus to increase.

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

Which of the following best describes valence electrons?

• electrons in the lowest energy level

• all of the electrons in the highest energy level

• all of the s & p electrons in the atom

• the s & p electrons in the highest energy level

By knowing the atomic number of a neutral atom, you know _____________________ .

• the number of neutrons in the atom

• the number of protons and electrons in the atom

• the number of protons and neutrons in the atom

• the number of all particles in the atom

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

What is the mass number and name of an element with 8 protons and 8 neutrons?

• Carbon-16

• Oxygen-16

• Oxygen-24

• Neon-8
