Back to Basics
The scientist that is credited with the organization of the periodic table.
Who is Dmitri Mendeleev?
What is the total distance from an atom's nucleus to the outermost shell of electrons?
What is decreases?
What is amount of energy required to remove an electron?
Reactivity of non-metals does this as it travels to the right of the periodic table.
What is increases?
Elements that belong to the same ___ share the same chemical properties.
What is groups?
The element that is considered to have the largest atomic radius.
What is Francium?
This happens to the electronegativity as you go from left to right across a period.
What is increases?
This is a positive ion.
What is a cation?
This is the definition of metallic character.
What is the tendency of an element to lose electrons and form positive ions or cations?
The most reactive elements with water.
The reason atomic radius generally increases as you move down a group on the periodic table.
What is moving down a group adds new electron shells, increasing the distance between the nucleus and outermost electrons?
This element has a higher electronegativity: N or Si.
What is N?
This is the element with the highest ionization energy.
What is Helium?
This element is more reactive than K: Rb or C.
What is Rubidium?
Elements from this group are nonflammable.
What are the Noble Gasses?
Which of these elements would have the smallest atomic radius: lithium (Li), potassium (K), or rubidium (Rb)?
What is Lithium?
These two elements have the lowest electronegativity.
What is Cesium and Francium?
`This element has a higher ionization energy: F or Ne.
What is Neon?
This is why copper was un-reactive in our lab.
What is it sits lower on the reactivity series than many other metals?
Elements from these two groups create docile salts when chemically bonded together.
What is Alkali Metals and Halogens?
Compare the relative atomic radii of oxygen (O) and sulfur (S) and explain your reasoning based on their positions on the periodic table.
What is sulfur has more electron shells, meaning its outermost electrons are further away from the nucleus, resulting in a larger atomic radius?
Electronegativity is the ability to do this when bonded to another atom.
What is attract electron towards itself?
What is fluorine has a much smaller atomic radius and a stronger nuclear pull?
This protetive covering is why aluminum did not react in our lab.
What is aluminum oxide?
