This particle has almost NO MASS, a NEGATIVE charge, and is located in a cloud or shells OUTSIDE the nucleus:
What is an ELECTRON?
He theorized and DESIGNED our modern Periodic Table:
Who was DMITRI MENDELEEV?
These are the THREE CLASSES of elements within the periodic table:
What are METALS, NON_METALS, and METALLOIDS?
Arsenic has 33 of these:
What are PROTONS (and sometimes electrons)?
This element is found at GROUP 16, PERIOD 2:
What is OXYGEN?
This particle with a POSTIVE CHARGE can be found INSIDE the nucleus:
What is a PROTON?
The name we use for the horizontal rows on the table:
What is a PERIOD?
These elements can be MALLEABLE and SHINY. They have HIGH CONDUCTIVITY. Their HIGH MELTING AND BOILING points keep them SOLID at standard temperatures. They are what we typically think of as representative of their class:
What are TRANSITION METALS?
The characteristics of METALS are:
What is often SHINY and BRIGHT, MALLEABLE & DUCTILE, as well as being excellent CONDUCTORS?
This HIGHLY REACTIVE METAL will explode in water! But, if it's pal chlorine BONDS with it, it will make your French fries delicious.
What is SODIUM?
The NEUTRON has this charge:
What is NO CHARGE or NEUTRAL?
The name we use for the vertical columns on the table:
What is a GROUP?
Last to be discovered these elements are extremely NONREACTIVE:
What are the NOBLE GASES?
The physical state is the transition metal MERCURY at room temperature:
What is LIQUID?
(they don't call it water silver - hydrargyrum - for no reason!)
This NONREACTIVE element is a LONER (single atoms), but when this GAS gets excited it lights up the Las Vegas Strip:
What is NEON?
The ATOMIC NUMBER tells us this:
What is the NUMBER OF PROTONS in the element?
Elements were initially placed in together based on:
What are SIMILAR PROPERTIES?
This group contains HIGHLY REACTIVE NON METALS with 7 valence electrons, they often join with ALKALI METALS:
What are the HALOGENS?
Because the NOBLE GASES have a FULL outer shell, they are:
What is NONREACTIVE?
This element that has properties of BOTH metals and nonmetals, is important in computing, and has a Valley named after it in California:
What is SILICON?
This FORMULA tells us how to calculate the number of NEUTRONS:
What is ATOMIC MASS - ATOMIC NUMBER?
The explanation of the order of arrangement of the individual elements, the thing that makes each unique, is this:
What is the ATOMIC NUMBER?
This family contains elements that are HIGHLY REACTIVE. They are RADIOACTIVE. Physically, they are SOFT, SILVERY, MALLEABLE, and DUCTILE. They can be referred to as "RARE EARTH" and hang out in a special place on the table:
What are the ACTINIDES?
The amount of energy ORBITALS that LITHIUM has:
What is TWO?
This HIGHLY REACTIVE, DIATOMIC, NON-METAL is a LIQUID at room temperature:
What is BROMINE?
