Physical Science Study Guide T2Q2

Front

What are Alkali Earth metals?

Back

Alkali Earth metals are the elements found in Group 2 of the periodic table, which include Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.

Front

Which group of elements are good conductors of electricity and heat?

Back

Metals are good conductors of electricity and heat.

Front

What is the atomic mass of Carbon?

Back

The atomic mass of Carbon is 12.

Front

Why do atoms bond?

Back

Atoms bond to achieve a full valence shell, which leads to greater stability.

Front

What are Noble gases?

Back

Noble gases are the elements found in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What are the properties of Non-Metals?

Back

Non-Metals are typically poor conductors of heat and electricity, and they can be gases, liquids, or brittle solids at room temperature.

Front

What is a valence shell?

Back

The valence shell is the outermost shell of an atom that contains the valence electrons, which are involved in chemical bonding.

Front

What is the difference between metals and non-metals?

Back

Metals are generally shiny, malleable, ductile, and good conductors of heat and electricity, while non-metals are dull, brittle, and poor conductors.

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.
