Periodic Table

Front

What is a halogen?

Back

Halogens are a group of elements in Group 17 of the periodic table, known for being highly reactive nonmetals. Examples include Fluorine, Chlorine, Bromine, and Iodine.

Front

Which element is an example of a noble gas?

Back

Xenon is an example of a noble gas, which are elements in Group 18 of the periodic table that are characterized by their lack of reactivity.

Front

What is an alkali metal?

Back

Alkali metals are the elements found in Group 1 of the periodic table, known for being highly reactive and having one electron in their outermost shell. Sodium is an example.

Front

Which element has similar chemical properties to Fluorine?

Back

Bromine has similar chemical properties to Fluorine, as they are both halogens.

Front

What are noble gases?

Back

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

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What is the significance of the groups in the periodic table?

Back

Groups in the periodic table indicate elements that have similar chemical properties and the same number of valence electrons.

Front

What are the properties of alkali metals?

Back

Alkali metals are soft, shiny, and highly reactive, especially with water, and they have low melting points.

Front

What is the difference between metals and nonmetals in the periodic table?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are usually dull, insulative, and brittle.

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.
