B.The lower the group number, the higher the period numbers, so the metalloids are found in a diagonal moving up from left to right.
C.The higher the group number, the lower the period numbers, so the metalloids are found in a diagonal moving down from left to right.
D.The higher the group number, the higher the period numbers, so the metalloids are found in a diagonal moving up from left to right.
Answer : The correct option is A.
Explanation :
Metalloid : Metaloids are the elements whose properties lie between the metals and non-metals.
There are six commonly elements which are boron, silicon, germanium, arsenic, antimony and tellurium. The rare elements are polonium and astatine.
The relation between the group number and period number of metalloid is that the lower the group number, the lower the period numbers and the metalloids are found in a diagonal moving down from left to right in the periodic table.
Answer:
(A) The lower the group number, the lower the period numbers, so the metalloids are found in a diagonal moving down from left to right.

The valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous property of metals.
Valence electrons are defined as a negatively charged particle that can be shared or transmitted between atoms that is found in the outermost shell of an atom. Valence electrons have a crucial role in determining how an atom will behave. The electrical configurations of elements can be used to find valence electrons. The total number of valence electrons in that element is then determined by counting the number of electrons in the outermost shell.
When newly treated, polished, or broken, a material takes on a bright look and conducts electricity and heat reasonably well. Metals are typically ductile and malleable. These traits are the result of the metallic bond that connects the atoms or molecules of the metal.
Thus, the valence electrons of metals jump easily to a higher energy orbital when light shines on them then they all fall emitting the excess energy as light show lustrous property of metals.

Answer:
Lustrous
Explanation:
Metals are lustrous which gives them a property of having Shiny surfaces
Answer:analysis
Explanation:
Answer: The number of atoms in given amount of oxygen gas is
Explanation:
According to the mole concept:
1 mole of a substance contains number of atoms.
We are given:
Moles of oxygen gas = 1 mole
So, the number of atoms that will be present in 1 mole of oxygen gas will be number of atoms.
Hence, the number of atoms in given amount of oxygen gas is
The bottle left outside will have the same vapor pressure as the bottle inside the room because they both contain water.
The bottle left outside will have higher vapor pressure than the bottle from the room.
No change to either bottle.
