Groups on Periodic Table

Front

What are groups on the periodic table?

Back

Groups are vertical columns in the periodic table that contain elements with similar chemical properties.

What is the significance of Group 1 in the periodic table?

Back

Group 1 is known as the alkali metals, which are highly reactive and include elements like lithium (Li), sodium (Na), and potassium (K).

Front

What are noble gases?

Back

Noble gases are elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell. Examples include helium (He) and neon (Ne).

What is the difference between a group and a period in the periodic table?

Back

A group is a vertical column of elements with similar properties, while a period is a horizontal row of elements that have increasing atomic numbers.

Front

What are alkaline earth metals?

Back

Alkaline earth metals are the elements in Group 2 of the periodic table, including magnesium (Mg) and calcium (Ca), known for being reactive but less so than alkali metals.

Front

Which elements are considered halogens?

Back

Halogens are the elements in Group 17 of the periodic table, including fluorine (F), chlorine (Cl), bromine (Br), and iodine (I), known for being very reactive.

Front

What is the reactivity of alkali metals with water?

Back

Alkali metals react vigorously with water, producing hydrogen gas and a metal hydroxide.

Front

What is the common property of elements in the same group?

Back

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

Front

What is the name of Group 3-12 elements?

Back

The elements in Groups 3-12 are known as transition metals, which have varying properties and are often good conductors of electricity.

Front

What is the atomic number?

Back

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