Wta happens whenan atom forms an ion?
When an atom forms an ion, it gains or loses electrons, resulting in a positive or negative charge. A positively charged ion is called a cation, and a negatively charged ion is called an anion. This change in the number of electrons affects the atom's chemical properties and reactivity.
The Lewis structure for a barium Ba ion looks like this Ba2 what best describes what happens when a barium atom forms an ion?
When a barium atom forms an ion, it loses two electrons to achieve a stable octet configuration like a noble gas. This results in the formation of a Ba2+ ion with a 0 oxidation state.
What is the difference between the formation of a positive ion and a negative ion?
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
What happens to electrons during ion formation?
During ion formation, electrons are either gained or lost by an atom. When electrons are lost, a positively charged ion forms (cation), and when electrons are gained, a negatively charged ion forms (anion). This process balances the number of protons and electrons in the atom to achieve a stable electron configuration.
In the reaction between bromine and sodium a bromine atom gains an electron and forms the bromine ion Br. what happens to bromine?
In the reaction, bromine gains an electron and forms a bromide ion (Br-). This results in a decrease in the oxidation state of the bromine atom from 0 to -1.
When Mg forms an ion will the ion be smaller or longer than the atom?
The ion has a smaller diameter.
What type of ion forms when atom lose electrons?
Losing an ion creates a positive charge. This forms a positive ion.
What happens when atom looses electron?
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
When a sulfur atom gains two electrons what happens to it?
It becomes a sulfur ion with a charge of -2.
When a lithium atom forms a Li plus ion the lithium atom does what?
THe lithoium atom has IONISED ( lost) an electron, to become the lithium ION.
In reaction between bromine and sodium bromine atom gains an electron and forms the bromide ion . What happens to bromine?
Bromine loses an electron and forms a bromide ion by gaining one electron in the reaction with sodium. Sodium donates its electron to bromine, making the bromine atom gain one electron and become a bromide ion during the reaction.
What happen when an atom forms an ion?
For an atom to form an ion, it has to either gain or lose one or more electrons. Usually this happens during a chemical reaction, when an element gains or loses electrons to achieve noble gas configuration.
