A. When elements are arranged in order of increasing atomic mass, there is a recurring pattern to their physical and chemical properties.
B. When elements are arranged in order of increasing atomic size, there is a recurring pattern to their physical and chemical properties within a group.
C. When elements are alphabetized, there is a periodic pattern to their physical and chemical properties within a period.
D. When elements are arranged in order of increasing atomic number, there is a recurring pattern to their physical and chemical properties.
**my answer: D.
is that right???
and i found this regarding #1:
The periodic law states that if the elements are arranged by atomic number, there will be repeating patterns of the properties of the elements.
so is my answer D?
Not the answer you are looking for? Search for more explanations.
#2: What is true of elements in a period on the periodic table?
A. They have similar properties.
B. They have similar names.
c. They have different properties that show no pattern.
D. They have different properties that repeat across the next period.
***i think it is either A or D... idk what do u think?
the prev #2 anyway
for this #2, i think it's A (like all the halogens are very flammable while all the noble gases don't react to anything)
okay, so my answers are:
oh wait, misread
yeah, you're right on both
wait so my answer are or arent these?
1= D. When elements are arranged in order of increasing atomic number, there is a recurring pattern to their physical and chemical properties.
2=A. They have similar properties.
