Do elements in the same group or elements in the same period have more in common?
Celindine
GROUPS have more in common than PERIODS. I don't know why, I just know the answer.

What is the more common name for group 7 metals?
The more common name for group 7 elements is the halogens
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
Why is there a sudden jump in the atomic radius in elements in group 18 and the next higher element in the next period in group 1?
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
Which pair of elements is more likely to form ionic compounds?
Group 1 or group 2 elements with group 16 or group 17 elements. In general, if the electronegativity difference between the two atoms is more than 1.7 in Pauling's scale, then the two atoms form ionic bond.
How does reactivity of elements change across the periodic table?
this is called periodicity, the chemical properties of elements as you go across a period. The reactivity would be very great at first, especially if you are only crossing main group elements, and then would become less reactive, then very reactive again, and then one group over they would be completely inert
What is the more common name for group 7 metals?
The more common name for group 7 elements is the halogens
Are Physical properties within a period are more alike than physical properties within a group?
No, the physical properties within a group are more alike than those of a period. This is because all elements in a group share the number of valence electrons.
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
What elements have more predictable properties main group elements or transition elements?
main group elements
List what group Tungsten is in?
Tungsten's group or family is metals. NOT metalloids!! It is a solid. More common elements in this group are Cobalt, Iron, and Sodium. and i swear this is true. (:
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Why is there a sudden jump in the atomic radius in elements in group 18 and the next higher element in the next period in group 1?
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.
Why group 12 is more reactive?
The elements from the group 12 are not the most reactive chemical elements.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What was a logical way to group elements as more and more elements were discovered?
The logical way is to be remembered that chemical properties of elements have a periodic character.
