Matter Interactions
A positive charge will _____ a negative charge.
A positive charge will ATTRACT a negative charge.
Mass is the amount of ____ in an object
Matter
In ____ mixtures, you can clearly see the components, while in _____ mixtures, components are not really visible.
Heterogeneous, homogeneous
____ is everything that has a mass, occupies a space in space and can be found in different states of aggregation.
Matter
Basic building block of matter and the smallest unit of a chemical element that still keeps its chemical properties.
Atom
Substances that allow an electrical current or heat to flow through them easily.
Conductors
____ properties depend on the perception of each person that measures them, while _____ properties are objective and use measuring units.
Qualitative, quantitative
This type of mixture has a solvent and a solute.
Solution
These substances cannot be separated by physical processes, only by chemical separation. One example is sucrose (C12H22O11).
Pure substances
Three subatomic particles present in the atom.
Protons, neutrons and electrons.
In this transfer, heat moves through proximity and is the primary method by which the Sun transfers heat to the Earth.
Radiation
____ properties depend on the amount of matter, while ____ properties do not depend on this amount.
Extensive, intensive
This mechanical separation technique separates insoluble solids from liquids or gases using a porous medium such as filter paper.
Filtration
A group of two or more atoms held together by chemical bonds, forming the smallest identifiable unit of a pure substance that keeps its unique composition and properties.
This theory says that the atom is a uniform sphere of positive charge with tiny, negatively charged electrons embedded throughout it. Hint: the name has to do with food.
Plum pudding model
Physical property of materials that allows them to be stretched thin when tensile stress is applied.
Ductility
_____ is the capacity of a substance to dissolve when you mix it with a liquid.
Solubility
This separation method is based on the force that results from spinning a mixture very quickly and separates small solid particles from a liquid.
Centrifugation
Amount of atoms in C₆H₁₂O₆
6 Carbons
12 Hydrogen
6 Oxygen
Three-dimensional regions around an atom's nucleus where there is a high probability (about 95%) of finding an electron.
Orbitals
Measure of the average kinetic energy of the tiny atoms and particles inside a substance
Temperature
What are organoleptic properties?
Organoleptic properties are the aspects of food, water, medicine, or other substances that you can experience and measure using your human senses: taste, sight, smell, and touch.
Separation method based on differences in the boiling points of components in a liquid homogeneous mixture. It is used for extracting essential oils from a flower.
Distillation
Electrons located in the outermost shell of an atom that can participate in forming chemical bonds.
Valence electrons
Even smaller particles that have been recently found in protons and neutrons. Hint: starts with q.
Quarks
