Atomic Structure
This particle of the atom always has a positive charge.
Protons
This element is the only atom that does not have two electrons in its inside shell.
Hydrogen
This property involves an element's ability to conduct moving electrons.
Conductivity
Whenever two or more atoms are bonded together, they are called this.
Molecules or Compounds
This science teacher developed the Periodic Table when he was writing a chemistry book in his own language.
Dmitri Mendeleev
This particle of the atom, located at the Nucleus, has no magnetic charge.
Neutrons
Elements in the Periodic Table can be classified into these THREE BASIC TYPES.
Metals, Non-Metals, Metalloids
The property of Malleability, the ability to be pounded into shapes, is a characteristic of this type of element.
Metals.
The formula for this electrically conductive molecule represents the ionic bond between Chlorine and Sodium.
NaCl
This college student who was bored at home during a lockdown developed a higher level of math - Calculus. This allowed him to eventually discover the Laws of Motion and Gravity.
Isaac Newton
These particles of an atom, which orbit the Nucleus, always have a Negative charge.
Electrons
The "Atomic Number" at the top of an element's entry in the Periodic Table refers to this unique characteristic about each element.
The number of Protons.
Mercury, a liquid at room temperature, undergoes this when it reaches 674.1 degrees Fahrenheit.
Boiling Point
This kind of molecular bond happens when a Non-Metal atom 'steals' an electron from a Metal atom.
Ion or Ionic Bond
This scientist worked his way through college cleaning the rooms of his classmates. He became famous when he used his new microscope to write and illustrate a book that revealed the microscopic world.
Robert Hooke
Electrons, having a Negative charge orbit the protons in different 'Energy Levels' called this.
Electron Shells
The "Periods" in the Periodic Table indicate this about each element in its row.
The number of Electron Shells.
Gallium, a "poor metal," reaches this at just 85 degrees Fahrenheit.
Melting Point
Water, consisting of one Oxygen atom bonding with the electrons of two Hydrogen atoms is a great example of this kind of molecular bond.
Covalent Bond
This astronomer used the new telescopes and mathematics to disprove the commonly held idea that the Universe revolved around Earth.
Nicolaus Copernicus
The term "Atomos" was used by this ancient scientist who was the first to think of matter as being made up of tiny "uncuttable" parts.
Democritus
The Atomic Mass number of an Element is literally the weight of that Element's atoms measured in this unit named after this scientist who discovered that atoms exist.
John Dalton
This metalloid element has just enough electrical conductivity that it can be used to make computer processors.
Silicon
With Metallic Bonds, the metal atoms freely exchange electrons back and forth between each other resulting in a constant flow of electrons called this.
Sea of Electrons
King Charles II insisted that this college dropout be given his Master's Degree for undertaking the huge task of mapping all of the visible stars in the Southern Hemisphere.
Edmond Halley
