What are Alkali Metals?

Back

Alkali Metals are a group of chemical elements in Group 1 of the periodic table, characterized by having one electron in their outermost shell. They are highly reactive and include elements like Lithium (Li), Sodium (Na), and Potassium (K).

What are Noble Gases?

Back

Noble Gases are a group of chemical elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell of electrons. Examples include Helium (He), Neon (Ne), and Argon (Ar).

Front

How many protons does Neon have?

Back

Neon has 10 protons.

Front

What is the atomic number of Arsenic?

Back

The atomic number of Arsenic is 33.

Front

What are Alkaline Earth Metals?

Back

Alkaline Earth Metals are the elements in Group 2 of the periodic table, characterized by having two electrons in their outermost shell. They include Beryllium (Be), Magnesium (Mg), and Calcium (Ca).

Front

What is the significance of atomic number?

Back

The atomic number of an element is the number of protons in its nucleus, which determines the element's identity and its position in the periodic table.

Front

What is the general trend in reactivity for Alkali Metals?

Back

Reactivity increases as you move down the group in Alkali Metals, with Lithium being the least reactive and Cesium being the most reactive.

Front

What distinguishes Halogens from other groups?

Back

Halogens are in Group 17 of the periodic table and are known for being highly reactive nonmetals, with seven electrons in their outermost shell. They include Fluorine (F), Chlorine (Cl), and Iodine (I).

Front

What is the electron configuration of Neon?

Back

The electron configuration of Neon is 1s² 2s² 2p⁶.

Front

What are Transition Metals?

Back

Transition Metals are elements found in Groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. Examples include Iron (Fe), Copper (Cu), and Gold (Au).
