Which group of elements could have the characteristic of brittle?
Metal
Nonmetal
Noah and Enrique conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table . Based on these observations, which sample is most likely a nonmetal?
Which element is classified as a metalloid?
Oxygen
Silicon
Gold
Sodium
A student is given four unknown elements and must classify each as a metal, metalloid, or nonmetal. The student observes the following properties: - Element 1: Shiny, conducts electricity, malleable - Element 2: Dull, does not conduct electricity, brittle - Element 3: Shiny, brittle, semiconducts electricity - Element 4: Gas at room temperature Which element is most likely a metalloid? Explain your reasoning.
Element 1, because it is shiny and conducts electricity.
Element 2, because it is dull and brittle.
Element 3, because it is shiny, brittle, and semiconducts electricity.
Element 4, because it is a gas.
You are given two unknown elements. Element X is shiny, malleable, and conducts electricity very well. Element Y is dull, brittle, and does not conduct electricity. How would you classify each element, and what evidence supports your classification?
X is a nonmetal, Y is a metal, because of their appearance.
X is a metal, Y is a nonmetal, because of their physical and electrical properties.
X is a metalloid, Y is a rare earth metal, because of their conductivity.
X is a rare earth metal, Y is a metalloid, because of their malleability.

What is the definition of a homogeneous mixture?
A mixture where the components separate into distinct layers according to density.
A mixture where the components are distributed unevenly and the composition varies throughout.
A mixture where the components are distributed uniformly and the composition is the same throughout.
A mixture where the components are distributed randomly and the composition changes at different points.
What is a homogenous mixture?
Something that you can mix and take out
You can mix it but it can not be separated
Heterogenous mixture
homogenous mixture is separating things and easily taking it out
