This is more than likely carbon, which is the building block of life. This is also the element of organic chemistry. It can be harmful in some of its compounds, see CO (carbon monoxide) for example.
sodium and lithium are both group 1 elements (like potassium)
You would see which group the element was in and then replace it with another element from the same group, as all elements in a group have similar properties. For example you could replace Sodium with Potassium as they are both in Group 1.
The representative element in period 4 group 14 is silicon (Si). It is located in Group 14 of the periodic table, also known as the carbon group. Silicon is a metalloid that exhibits properties of both metals and nonmetals.
Bromine, group 17; Mercury, group 12. Both are liquids at STP
The pattern between calcium and gallium is that they both belong to the same group on the periodic table, Group 2. They both have similar outer electron configurations and exhibit similar chemical properties in terms of reactivity and bonding. However, they have different atomic numbers and physical properties due to the difference in their atomic structures.
They are both in Group 2
The element in the same group as Al is boron (B). They both belong to Group 13 in the periodic table.
Zn=Zinc, which is a solid; Hg=Mercury, which is a liquid. They are both in group 12.
sodium and lithium are both group 1 elements (like potassium)
Phosphorus has the most similar properties to nitrogen. They are both nonmetals located in the same group (Group 15) of the periodic table, sharing some chemical properties such as forming multiple bonds and acting as essential elements for biological processes.
Carbon (C) is in the same group as Silicon (Si) because they both belong to Group 14 of the periodic table.
You would see which group the element was in and then replace it with another element from the same group, as all elements in a group have similar properties. For example you could replace Sodium with Potassium as they are both in Group 1.
Sodium is an element that is similar to potassium. Both are alkali metals in group 1 of the periodic table and have similar chemical properties.
Visible light is both harmful and helpful. It provides us with the ability to see and is essential for many biological processes, but excessive exposure to certain wavelengths of visible light can also cause damage to our eyes and skin.
The representative element in period 4 group 14 is silicon (Si). It is located in Group 14 of the periodic table, also known as the carbon group. Silicon is a metalloid that exhibits properties of both metals and nonmetals.
lion are useful and harmful
Chlorine is in the same group as fluorine, as they both belong to Group 17 (halogens) of the periodic table. Meanwhile, chlorine is in the same period as sulfur, as they both are on the third period of the periodic table.
