Unit 1 Review 8.5 ABC

HOW DO I DETERMINE THE NUMBER OF VALENCE ELECTRONS?

• The period # on the periodic table

• The group # on the periodic table

• The atomic # on the periodic table tile

• The atomic mass on the periodic table tile

WHAT IS THE MOST REACTIVE GROUP ON THE PERIODIC TABLE?

• Group 18 because the outer shell is full.

• Group 1 and Group 17 are both highly reactive

• Group 2 is the most reactive

• Group 16 is the most reactive

WHAT IS THE LEAST REACTIVE GROUP?

• Group 18 because the outer electron shell is full

• Group 1 because the atoms 1 electron in its outer shell

• Group 17 because the atoms need only 1 more electron in their outer shell

• Group 2 because the atoms have 2 electrons in their outer shell

WHAT IS THE MAXIMUM NUMBER OF VALENCE ELECTRONS FOR AN ELEMENT?

• 1 valence electron

• 3 valence electrons

• 4 valence electrons

• 8 valence electrons

ATOMS HAVE 3 DIFFERENT SUBATOMIC PARTICLES, WHAT ARE THEY?

• protons, electrical, and neutrals

• protons, neutrons, and electrons

• nucleus, cell wall, and protons

• protons, nucleus, and cytoplasm

WHAT 2 SUBATOMIC PARTICLES MAKE UP THE NUCLEUS?

• electrons and valence electrons

• protons and electrons

• neutrons and electrons

• protons and neutrons

WHICH SUBATOMIC PARTICLE MATCHES THE ATOMIC NUMBER SO YOU CAN IDENTIFY AN ATOM?

• protons

• neutrons

• electrons

• valence electrons

IF I HAVE 8 PROTONS, WHAT AM I? WHAT AM I CLASSIFIED AS?

• Helium - nonmetal

• Iron - metal

• Oxygen - nonmetal

• Neon - nonmetal

IF I HAVE 20 PROTONS, WHAT AM I? WHAT AM I CLASSIFIED AS?

• Calcium - metal

• Iron - metal

• Oxygen - nonmetal

• Neon - nonmetal

IF I HAVE 13 PROTONS, WHAT AM I? WHAT AM I CLASSIFIED AS?

• Calcium - metal

• Carbon - nonmetal

• Aluminum - metal

• Neon - nonmetal
