Mendeleev developed his periodic table after what?
What is He modeled his table after a card game similar to solitaire.
100
Refer to your periodic table, in what period and group is sulfur?
What is period 3, group 16
100
Describe metals.
What is elements that are good conductors of heat and electric current. Usually on the left side of periodic table.
100
Give an example of an ionic compound.
What is metals + nonmetals
100
How many valence electrons are in chlorine, Draw Bohrs model, and tell what family it is in.
What is 7, answers must have picture of bohrs model, and halogens
200
When Mendeleev developed his periodic table how many elements had been discovered?
What is 63
200
How many valence electrons are in metals of the alkaline earth family?
What is 2
200
Describe alkali metals
What is the elements in Group 1A. These metals have a single valence electron and are extremely reactive.
200
Metals typically become positively charged particles called
What is cations
200
What is a molecule?
What is A neutral group of atoms that are joined together by one or more covalent bonds
300
How was Mendeleev able to predict the properties of elements that had not been discovered yet?
What is based on his prediction on the properties of nearby elements and other elements in the same column
300
How does the reactivity of alkali metals vary?
What is The reactivity increases as you go down the group.
300
Describe nonmetals
What is elements that are poor conductors of heat and electric current. Usually on the right side of periodic table
300
What type of bond forms when electrons are transferred from one atom to another?
What is ionic bond
300
Why are noble gases considered nonreactive?
What is They have 8 valence electrons, and do not want to react to gain or lose valence electrons because they are already stable.
400
How did Mendeleev organize the elements into rows and columns in his periodic table?
What is in order of increasing mass so that elements with similar properties were in the same column
400
What family of elements is found in neon lights?
What is noble gases
400
What is an electron that is in the highest occupied energy level of an atom.
What is valence electron
400
What happens to the charge on atoms when they form a polar covalent bond?
What is The atom with the greater attraction for electrons has a partial negative charge, and the other atom has a partial positive charge.
400
How are metals and nonmetals physical properties different?
What is metals are ductile, malleable, and good conductors of heat and electricity, nonmetals are not.
500
On the modern periodic table, how are the elements arranged or ordered?
What is by increasing atomic number
500
Which elements on the periodic table has chemical properties that are most similar to carbon? Name 2
What is silicon, germanium, tin
500
What is an arrangement of elements in columns, based on a set of properties that repeat from row to row
What is periodic table
500
Which type of bond is the hardest to break?
What is covalent bond
500
