Total questions: 10
Worksheet time: 6mins
Why are both hydrogen and cesium s-block elements, when hydrogen has one electron and cesium has 55?
All blocks contain at least one element from each period.
Blocks of elements on the periodic table are based only on an element's valence electrons.
The s-block includes only the most reactive elements.
They have identical electron configurations.
Atoms of elements in group 1 have ____________.
one electron in their outermost energy level
two electrons in their outermost energy level
seven electrons in their outermost energy level
eight electrons in their outermost energy level
Which of the blocks on the periodic table contains the most elements?
s block
p block
d block
f block
What makes the d block wider than either the s block or the p block?
The d sub-orbital can hold ten electrons, making the d block ten elements wide.
The d block is the most researched area of the periodic table.
The elements in the d block are more important than the elements in the rest of the table.
The elements in the d block are all metals.
From the table below, determine the atomic number of the noble gas at the end of period 5.
