i love skeppy
the following elements as akali, alkaline earth metals based on their positions in the periodic table
Section 3 review classify the following element as alkali alkaline earth or transition metal based on their position in the periodic table
im not good at this stuff i just wanted to put somtehing and fit in :(
A- transition metal
B- alkali metal
C- Alkaline earth metals
D- transition
You Welcome.
To determine whether an element is an alkali metal, alkaline earth metal, or a transition metal based on its position in the periodic table, you can look at its group number.
A) Iron (Fe) is a transition metal. It is located in Group 8 on the periodic table, which is also known as the "transition metals" group. Transition metals are found in Groups 3 to 12 and are characterized by their ability to form various oxidation states.
B) Potassium (K) is an alkali metal. It is located in Group 1 on the periodic table, also referred to as the "alkali metals" group. Alkali metals are highly reactive, soft metals that are known for their low melting points and ability to readily lose their valence electron.
C) Strontium (Sr) is an alkaline earth metal. It is located in Group 2 on the periodic table, which is known as the "alkaline earth metals" group. Alkaline earth metals are also reactive but less so than alkali metals. They have two valence electrons and are slightly harder and denser than alkali metals.
D) Platinum (Pt) is a transition metal. It is located in Group 10 on the periodic table, which is part of the transition metals group.
So, to summarize:
A) Iron (Fe) is a transition metal.
B) Potassium (K) is an alkali metal.
C) Strontium (Sr) is an alkaline earth metal.
D) Platinum (Pt) is a transition metal.
