The most important criteria is the similarities between chemical properties.
We consider factors such as atomic number, number of electrons in the outer shell, and physical and chemical properties to determine which group an element belongs to. These characteristics help to group elements with similar properties together, making it easier to understand and predict their behavior.
The element in the same group as Al is boron (B). They both belong to Group 13 in the periodic table.
It would belong to group XVI, the group with oxygen.
group 1, or 2, or ... 18 depends on its properties.
Titanium belongs to the family of transition metals.
²⅔
this element belongs in the group of metals
group 16
Group 15
The element neon belong to the periodic group of noble gases, these are also called inert gasses. The element when under standard condition has no odor, no color and has a monatomic gas.
this element belongs in the gruop of metals
As==Arsenic. This element is a metaloid.
We consider factors such as atomic number, number of electrons in the outer shell, and physical and chemical properties to determine which group an element belongs to. These characteristics help to group elements with similar properties together, making it easier to understand and predict their behavior.
Oxygen is the first element in group 16 of the periodic table
The element in the same group as Al is boron (B). They both belong to Group 13 in the periodic table.
Platinum is in Group 10, , and Period 6.
Helium is the element that doesn't belong in a group with any others on the periodic table. It is part of Group 18, the noble gases, which are characterized by their stable and unreactive nature.
