What else can I help you with?
Which elements woukd you expect to be similar to technetium?
Rhenium is the element most similar to technetium in terms of chemical properties and behavior due to their adjacent positions in the periodic table. Both technetium and rhenium are transition metals with similar electron configurations, allowing them to exhibit analogous oxidation states and reactivity. Additionally, both elements are used in nuclear medicine applications for diagnostic imaging.
Why would you expect lithium and sulfur to have different chemical and physical properties?
Lithium and sulfur are different elements with unique atomic structures, leading to variations in chemical and physical properties. Lithium is a metal with low density and a tendency to form ionic compounds, while sulfur is a non-metal with a higher molecular weight and the ability to form covalent compounds. This results in differences such as lithium being a solid at room temperature while sulfur is a yellow solid or gas.
Would you expect nitrogen and argon to have similar chemical properties?
No, nitrogen and argon have different chemical properties. Nitrogen is a reactive diatomic nonmetal, while argon is a noble gas known for its inertness. Nitrogen tends to form compounds, while argon is largely unreactive.
If two materials are made from different kinds of atom what else should you expect to be different?
Pretty much everything. Density, conductivity, elasticity, hardness etc etc.
How similar might you expect the chemical properties of gallium and indium to be?
Gallium and indium are both in the same group of the periodic table (Group 13), so they have similar chemical properties. Both elements are soft metals with low melting points and are often used in electronic applications due to their unique properties. However, gallium is more reactive than indium and has a lower melting point.
Where on the periodic table would you expect to find elements with similar properties and chemical characteristics?
Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
What elements would you expect to be similar to technetium?
Rhenium is similar to technetium.
Which elementswould you expect to be similar to technetium?
Technetium is chemically similar to manganese and rhenium.
What physical and chemical properties would you expect to find in two different samples of a pure substance?
Two different samples of a pure substance would have the same physical properties, such as color, melting point, boiling point, and density. Their chemical properties, like reactivity and ability to form specific compounds, would also be identical. Variations in the samples' properties could indicate impurities present.

Rhenium is the element most similar to technetium in terms of chemical properties and behavior due to their adjacent positions in the periodic table. Both technetium and rhenium are transition metals with similar electron configurations, allowing them to exhibit analogous oxidation states and reactivity. Additionally, both elements are used in nuclear medicine applications for diagnostic imaging.
What do the elements nickel and technetium have in common?
Technetium is 1 down 4 left of Nickel, Both are transition metals, both are silver and shiny, I don't know exactly what kind of answer you want
Would you expect neodymium and uranium to similar properties?
Uranium and neodymium are very different chemical elements.
What would you expect to happen if you mixed argon and sodium together?
Since argon is a noble gas, I wouldn't expect much to happen; specifically, I wouldn't expect any chemical reaction.

Pretty much everything. Density, conductivity, elasticity, hardness etc etc.
What chemical properties would you expect caesium to have?
Caesium is freshly cut, it have a metallic shine, but this disappears rapidly due to reaction of exposed metal surface with oxygen in the air
