|---|---|---|---|---|---|
| WHAT IS THE PERIODIC TABLE? | A CHART USED TO ORGANIZE ELEMENTS INTO GROUPS AND PERIODS
🗑
|
||||
| WHAT ARE THE COLUMNS ON THE PERIODIC TABLE CALLED? | GROUPS OR FAMILIES
🗑
|
||||
| WHAT DO GROUPS ON THE PERIODIC TABLE HAVE IN COMMON? | THEY HAVE THE SAME NUMBER OF VALENCE ELECTRONS SO THEY HAVE SIMILAR CHEMICAL AND PHYSICAL PROPERTIES
🗑
|
||||
| WHAT DO PERIODS ON THE PERIODIC TABLE HAVE IN COMMON? | THEY HAVE THE SAME NUMBER OF ENERGY LEVELS (SHELLS) TO HOLD THEIR ELECTRONS
🗑
|
||||
| WHAT IS THE MOST REACTIVE GROUP OF METALS ON THE PERIODIC TABLE? | ALKALI METALS - GROUP 1 - THEY ONLY HAVE ONE VALENCE ELECTRON
🗑
|
||||
| WHAT IS THE MOST STABLE GROUP/FAMILY ON THE PERIODIC TABLE? | NOBEL GASSES - GROUP 18
🗑
|
||||
| WHY ARE NOBEL GASES UNREACTIVE? | THEIR VALENCE SHELL IS FULL - THEY HAVE 8 VALENCE ELECTRONS
🗑
|
||||
| HOW MANY VALENCE ELECTRONS DO ATOMS NEED IN ORDER TO BE THE MOST STABLE? | 8
🗑
|
||||
| HOW MANY VALENCE ELECTRONS DOES CHLORINE HAVE? | 7
🗑
|
||||
| HOW MANY VALENCE ELECTRONS DOES SILICON HAVE? | 4
🗑
|
||||
| HOW MANY VALENCE ELECTRONS DOES FRANCIUM HAVE? | 1
🗑
|
||||
| WHAT IS THE OVERALL CHARGE OF THE NUCLEUS? | POSITIVE
🗑
|
||||
| WHAT IS THE OVERALL CHARGE OF THE ELECTRON CLOUD? | NEGATIVE
🗑
|
||||
| HOW DO YOU KNOW HOW MANY PROTONS AN ATOM HAS? | LOOK AT THE ATOMIC NUMBER
🗑
|
||||
| HOW DO YOU FIND THE NUMBER OF ELECTRONS AN ATOM HAS? | LOOK AT THE ATOMIC NUMBER - ASSUME ATOM IS NEUTRAL SO # OF PROTONS = # OF ELECTRONS
🗑
|
||||
| HOW DO YOU FIND THE NUMBER OF NEUTRONS AN ATOM HAS? | ROUND THE MASS THEN SUBTRACT THE ATOMIC NUMBER
🗑
|
||||
| HOW MANY PROTONS DOES SODUIM HAVE? | 11
🗑
|
||||
| HOW MANY ELECTRONS DOES SODIUM HAVE? | 11
🗑
|
||||
| HOW MANY NEUTRONS DOES SODIUM HAVE? | 12
🗑
|
||||
| FLUORINE HAS 7 VALENCE ELECTRONS AND LITHIUM HAS 1 VALENCE ELECTRON - HOW WILL THEY REACT? | FLUORINE WILL GAIN LITHIUMS 1 ELECTRON
🗑
|
||||
| WOULD YOU EXPECT FLUORINE TO REACT WITH MAGNESIUM? | NO - FLUORINE ONLY NEEDS TO GAIN 1 ELECTRON IN ITS VALENCE SHELL AND MAGNESIUM NEEDS TO LOOSE 2
🗑
|
||||
| HOW DO YOU KNOW IF AN ATOM WILL GAIN, LOOSE, OR SHARE ELECTRONS? | IF AN ATOM HAS 1,2, OR 3 VALENCE ELECTRONS IT WILL LOOSE ELECTRONS. IF AN ATOM HAS 4 VALENCE ELECTRONS IT WILL SHARE, AND IF AN ATOM HAS 5,6, OR 7 VALENCE ELECTRONS IT WILL GAIN
🗑
|
||||
| WHAT NOBEL GAS HAS 6 ENERGY LEVELS FOR THEIR ELECTRONS? | RADON
🗑
|
||||
| NAME THE ELEMENT THAT IS GROUP 14 PERIOD 3 | SILICON
🗑
|
||||
| A SCIENTIST IS LOOKING FOR AN ELEMENT THAT REACTS LIKE MAGNESIUM BUT HAS A LOWER ATOMIC MASS - WHAT WOULD YOU RECOMMEND? | BERYLLIUM
🗑
|
||||
| WHAT IS MORE SIMILAR TO BISMUTH - NITROGEN OR CAESIUM? | NITROGEN - THEY ARE IN SAME FAMILY
🗑
|
||||
| HOW IS THE PERIODIC TABLE ORGANIZED? | BY ATOMIC NUMBER
🗑
|
||||
| HOW CAN YOU FIND THE NUMBER OF ELECTRONS A NEUTRAL ATOM HAS? | LOOK AT THE ATOMIC NUMBER, IF NEUTRAL PROTONS = ELECTRONS
🗑
|
||||
| WHAT DETERMINES AN ELEMENTS IDENTITY? | PROTONS
🗑
|
||||
| WHAT DETERMINES AN ELEMENTS REACTIVITY? | VALENCE ELECTRONS
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
