Front

What are the most reactive metals in the periodic table?

Back

The most reactive metals are found in Group 1 (alkali metals), such as lithium, sodium, and potassium.

Front

How do you order liquids from most dense to least dense?

Back

To order liquids by density, you compare their mass per unit volume. For example, if liquid 4 is denser than liquid 3, which is denser than liquid 2, and liquid 1 is the least dense, the order is 4, 3, 2, 1.

Front

What type of seismic wave arrives first after an earthquake?

Back

The first seismic wave to arrive after an earthquake is the P Wave (Primary Wave), which is a compressional wave.

Front

Which element is less electronegative: Niobium (Nb) or Strontium (Sr)?

Back

Strontium (Sr) is less electronegative than Niobium (Nb).

Front

What is another name for heat energy?

Back

Heat energy is also called thermal energy.

Front

What is the definition of electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What are the characteristics of alkali metals?

Back

Alkali metals are highly reactive, have one electron in their outer shell, and are soft and shiny.

Front

What is the difference between P Waves and S Waves?

Back

P Waves are compressional waves that travel faster and can move through solids and liquids, while S Waves are shear waves that only travel through solids.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is the significance of the periodic table groups?

Back

Elements in the same group of the periodic table have similar chemical properties and the same number of valence electrons.
