increases As you go down a family of metals, the reactivity ________
The periodic table is made up mostly of which type of element? metals
decreases As you go down a family of nonmetals, the reactivity _________
As you go from the left to the right across a period, the electronegativity increases
Electronegativity A measure of the ability of an atom in a chemical compound to attract electrons
metals The periodic table is made up mostly of which type of element?
metalloids Elements that have properties of both metals and nonmetals.
ionization energy trend decreases from top to bottom in a group; increases from left to right in a period
gain Nonmetals _____ electrons to become stable and become anions
Measure of the tendency of an atom to attract a bonding pair of electrons electronegativity
decreases As you go from the left to the right across a period in the table, the atomic radius
increases As you go from the top to the bottom in a group, the atomic radius
energy involved in gaining an electron to become a negative ion is known as electron ______ affinity
The amount of energy required to remove an electron from an atom is known as _____ energy ionization
metal atoms tend to ____________ electrons to nonmetals when they react transfer
metals are _____ meaning they can be hammered into thin sheets and bent malleable
increases As you go from the left to the right across a period, the electronegativity
luster of minerals that is not shiny like metal and is not considered malleable and Dull in appearance nonmetallic
decreases As you go from the top to the bottom of a family, the electronegativity
Group 2A elements that are somewhat reactive and found in the earth's crust. alkaline earth metals
Halogens Contains nonmetals, 7 valence electrons in it's outermost energy level. Very reactive
increases As you go from the left to the right across a period, ionization energy
decreases As you go from the top to the bottom of a family, ionization energy
Nobel Gases Atoms that have completely filled energy levels or that eight electrons in their outermost energy level - do not easily lose electrons. ( Group 8 or 18 )
Periods Horizontal rows on the periodic table
the elements most likely to form more than one type of ion and located in the three rows of elements in the middle of the periodic table are the ____ metals transition
vertical columns on periodic table of elements groups
elements with similar properties families
the rule that States atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons octet

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
