Who arranged the first periodic table.
Mosely
Einstein
Mendeleev
Bohr
In Mendeleev's periodic table elements were ordered by increasing...
Shielding effect
Eletronegitivity
Atomic Weight
Metallic Character
Why were there blank spaces left in Mendeleev's periodic table?
He didn't know what to put there.
Undiscovered elements not yet known.
Multiple elements could have fit
He forgot to add the elements in.
In the modern periodic table elements are arranged by:
atomic mass
atomic number
valence electrons
number of isotopes
Who arranged the periodic table by increasing atomic number?
Mendeleev
Rutherford
Bohr
Mosely
Why did scientists need/want to organize the elements?
Scientists like things organized
make it easier to understand the elements
have one list of the known elements.
none of the above
How many block(s) are there in the periodic table ?
5
8
4
118
Which block is found in groups 1-2 and what type elements do they hold ?
S-block which contains metals
D-block which contains non-metals
F-block which contains transition metals
P-block which contains Lanthanides & Actinides
In group 1 and group 2 what are the names of those metals
Group 1:Alkaline Earth Metals,Group 2:Alkali Metals
Group 1:Alkali Metals,Group 2:Alkaline Earth Metals.
They Don"t have names
Which block is found in groups 3-12 ?
S-block
F-block
P-block
D-block
In this block elements are classified as 'Metalloids' or 'semiconductors'
S-block
F-block
P-block
D-block
Elements found in d-block are called transition metals why is that ?
*transition means:changing from one state or condition to another.
Because of the way they react with the environment they transition into a new molecular structure
Because they transition from Metals to Non-Metals
Because it sounds cool
Which block is found in groups 13-18 and what type of elements do they hold
F-block which contain Lanthanides & Actinides
S-block which Contain Transition Metals
P-block which contain Non-Metals
D-block which contain nothing
In p-block there two groups that have a unique name what are those groups and what are the called ?
Group 1:Alkali metals
Group 2: Alkaline Earth Metals
Group 17 the Halogen Family (which are very reactive because they have 7 valence electons)
Group 18 the noble gases (which are very stable because they have a complete outer-shell)
