what is the name of group 18
Nobel gases
What is the energy level of Carbons valence electrons
2
which atom has a greater atomic radius and why. Ca or Sr
Sr. More energy levels
How many valance electrons does lithium have
1
This group is very unreactive
Nobel gases
Members of this group have only 1 valance electron
alkali metals
what is the energy level of calcium's valence electrons
4
Which element has greater electronegativity and why. Al or S
S because it is smaller
How many valance electrons does phosphorus have
5
This group will give away 2 electrons when reacting
Alkaline earth metals
Some members of this group are radioactive
actinides
How many energy levels does Cl contain
3
Which atom has a greater ionization energy and why. O or F
F because its electrons are closer to the nucleus
Give the number of valence electrons of Na and S
1 and 6
what row of the periodic table (1-18) will gain 3 electrons when reacting
group 16
members of this group are very reactive nonmetals
halogens
How many energy levels does radon contain
6
which element has the greatest electron affinity and why? Ge or Pb
Ge because it is smaller so when an electron is added it is closer to the nucleus. Closer to the nucleus means a greater attraction, therefore more energy is released
Give the number of valance electrons of Ca, Ga, and Kr
2, 3, and 8
Which 3 rows/groups of the periodic table (1-18) contain metals, semimetals, and nonmetals
rows 14, 15, and 16
Some of the elements in the group will react with water but not all
Alkaline earth metals
what is the highest energy level present in Nickel
4
Which element has the greatest size and why? S, Se, or Te
Te because it has the most energy levels
Give the valance electrons of B, C, N, and O
3, 4, 5, 6
Which group contains the most electronegative elements
halogens
