Respuesta :
im guessing it's (a) since the numbers go in chronological order and you read the periodic table left to right
Answer : The correct option is, (1) The lower the group number, the lower the period numbers, so the metalloids are found in a diagonal moving down from left to right.
Explanation :
Metalloids : These are the elements which shows both the property of metals and non-metals that means the metalloids are present in between the metals and non- metals elements.
Boron, silicon, germanium, arsenic, antimony, tellurium and polonium are the metalloids.
In the periodic table, the metals are present on the left side, non-metals are present on the right side and the metalloids are present between the metals and non-metals.
The relation between the group number and the period number is :
The lower the group number, the lower the period numbers. So, the metalloids are found in a diagonal moving down from left to right.
Hence, the correct option is, (1)
The periodic table is also shown below.
