What else can I help you with?
Do the size of cations increase or decrease?
Cations generally decrease in size as you move from left to right across the periodic table due to increasing nuclear charge pulling the electrons closer to the nucleus. However, cations increase in size as you move down a group due to the addition of electron shells.
What happens to the ionic radius values of the cations( plus ) as you move across period 2?
As you move across period 2 from lithium (Li) to neon (Ne), the ionic radius of cations generally decreases. This is due to the increasing positive charge in the nucleus, which pulls the electrons closer to the nucleus and reduces the size of the cation. Additionally, the increase in effective nuclear charge without a corresponding increase in electron shielding causes the ionic radius to shrink. Consequently, cations like Li⁺ are larger compared to cations like N³⁺ or O²⁺ in the same period.
Where does anions and cations come into electrolysis?
Anions are negatively charged ions that move to the anode during electrolysis, where they give up electrons. Cations are positively charged ions that move to the cathode during electrolysis, where they gain electrons. This movement and exchange of ions is essential for the transfer of charge and the chemical reactions that occur during electrolysis.
What happens to the ionic radius values of the cations(-) as you move across period 2?
The ionc radius of lithium is bigger compared to beryllium.
Do alkali metals generally make anions or cations?
Alkali metals generally form cations by losing their outermost electron to achieve a stable electron configuration.
What is the function of a salt-bridge in an electrochemical cell?
The salt bridge allows cations to move in the galvanic cell. Electrons move from the anode to the cathode, leaving cations behind. The salt bridge allows for a balance of cations and anions to occur to continue the flow of electrons.

What Cations bonded together by mobile electrons examples?
An example of cations bonded together by mobile electrons is metallic bonding. In metallic bonding, metal cations are surrounded by a "sea" of delocalized electrons that move freely throughout the structure, holding the cations together in a lattice. This is commonly seen in metals such as copper, iron, and aluminum.
What elements or molecules are cations?
Cation is a positive ion, not an element; for metals the symbol is Mex+.
Is a flame test for cations?
yes, for cations
What charge do cations have?
Cations have a positive charge.
