Bromine
Which particle is larger in the atom/ion pair; S or S2-?
What is S2-?
As you move across the periodic table atoms tend to get smaller because, ______________.
the atoms have more protons.
Atomic radius generally increases as we move __________.
down a group and from right to left across a period
Metals are good conductors of heat and electricity. TRUE OR FALSE
True
Which particle is larger in the atom/ion pair; Ca2+ or S2-?
S2- is larger
Both have the same number of electrons, but Ca2+ has more protons pulling on less than the usual number of electrons, so they can put them harder.
Which of the following has the LARGEST atomic radius: Oxygen, Sulfur, Selenium, Tellurium
Tellurium
Describe the trend of Atomic Radius down a group and across a period?
Atomic Radius increases down a group and decreases across a period
Which of the following will have a larger radius than Zinc?
Gallium
Aluminum
Magnesium
Strontium
Strontium
Which of the following has the SMALLEST atomic radius Ne or Na1+?
Na1+ is smaller
Same number of electrons, but sodium ion has more protons pulling on less than usual number of electrons, pulling them closer.
Which particle has the larger radius in each atom/ion pair; Na and Na+?
What is Na?
What is an "Atomic Radius"?
Half the diameter of an atom
The more protons there are, the ____ the pull
stronger
Which of the following has the LARGEST atomic radius: Xe or I1-?
I1- is larger
Same number of electrons, but I1- has less protons to pull on more electrons.
