Cations are positively charged ions that are formed when an atom loses electrons. They are smaller than their parent atoms due to the loss of electrons, and they are attracted to the cathode in electrolysis. Cations play a crucial role in various chemical reactions and in the functioning of biological systems.

Why Walden's rule not applicable to small size cations?
Walden's rule states that ions of similar size have similar properties. However, for small cations, the high charge density can lead to significant interactions with surrounding molecules, causing deviations from Walden's rule. These interactions can affect properties such as solubility and reactivity, making the rule less applicable for small cations.
Which tool would be used to find information on which cations or anions will replace other cations or anions in a chemical reaction?
A solubility chart or a table of standard reduction potentials can be used to determine which cations or anions will replace others in a chemical reaction depending on their reactivity and solubility properties.
Do metalloids form cations?
Metalloids generally do not form cations as readily as metals do due to their intermediate properties between metals and nonmetals. However, under certain conditions, metalloids like boron and silicon can form cations by losing electrons to achieve a stable electron configuration.
What is lattice of cations?
A lattice of cations refers to a repeating three-dimensional arrangement of positively charged ions within a crystal structure. This lattice helps to stabilize the crystal by balancing the charges of the positively charged cations with negatively charged anions. It is a key component in determining the physical and chemical properties of a compound.
What physical properties are shared by most meatles?
Most metals share properties such as high electrical conductivity, high thermal conductivity, malleability, ductility, and shiny appearance. They also tend to form cations by losing electrons in chemical reactions.
What is a property of metals?
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.

How are the cations different in each type of binary compound?
In ionic binary compounds, cations are positively charged ions that give up electrons to become stable. The type of cation present in a binary compound depends on the elements involved in the compound. For example, sodium forms Na+ cations while magnesium forms Mg2+ cations. Each cation has a different charge and properties based on its atomic structure.

This lattice helps to stabilize the crystal by balancing the charges of the positively charged cations with negatively charged anions. It is a key component in determining the physical and chemical properties of a compound.
How are cations identified?
Cations can be identified by performing chemical tests that specifically react with cations, such as flame tests, precipitation reactions or complexation reactions. These tests are based on the unique properties of different cations to form characteristic colored precipitates or complexes. Additionally, analytical techniques such as ion exchange chromatography or mass spectrometry can be used for cation identification.
Which cations are acidic?
Hydrogen ion (H+) is a commonly recognized acidic cation. Other cations like aluminum ion (Al3+) and zinc ion (Zn2+) can also exhibit acidic properties based on their behavior in solutions.
Is a flame test for cations?
yes, for cations
What charge do cations have?
Cations have a positive charge.

What chemical properties are shared by most metals?
Metals conduct electricity. Metals ionise [lose one or more electrons] to form positively charged ions - cations.
