100

A positive charge will _____ a negative charge.

A positive charge will ATTRACT a negative charge.

100

Mass is the amount of ____ in an object

Matter

100

In ____ mixtures, you can clearly see the components, while in _____ mixtures, components are not really visible.

Heterogeneous, homogeneous

100

____ is everything that has a mass, occupies a space in space and can be found in different states of aggregation.

Matter

100

Basic building block of matter and the smallest unit of a chemical element that still keeps its chemical properties.

Atom

200

Substances that allow an electrical current or heat to flow through them easily.

Conductors

200

____ properties depend on the perception of each person that measures them, while _____ properties are objective and use measuring units.

Qualitative, quantitative

200

This type of mixture has a solvent and a solute.

Solution

200

These substances cannot be separated by physical processes, only by chemical separation. One example is sucrose (C12H22O11).

Pure substances

200

Three subatomic particles present in the atom.

Protons, neutrons and electrons.

300

In this transfer, heat moves through proximity and is the primary method by which the Sun transfers heat to the Earth.

Radiation

300

____ properties depend on the amount of matter, while ____ properties do not depend on this amount.

Extensive, intensive

300

This mechanical separation technique separates insoluble solids from liquids or gases using a porous medium such as filter paper.

Filtration

300

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.

Molecule
300

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

400

Physical property of materials that allows them to be stretched thin when tensile stress is applied.

Ductility

400

_____ is the capacity of a substance to dissolve when you mix it with a liquid.

Solubility

400

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

400

Amount of atoms in C₆H₁₂O₆ 

6 Carbons

12 Hydrogen

6 Oxygen

400

Three-dimensional regions around an atom's nucleus where there is a high probability (about 95%) of finding an electron.

Orbitals

500

Measure of the average kinetic energy of the tiny atoms and particles inside a substance

Temperature

500

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.

500

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

500

Electrons located in the outermost shell of an atom that can participate in forming chemical bonds.

Valence electrons

500

Even smaller particles that have been recently found in protons and neutrons. Hint: starts with q.

Quarks
