What does the roman numeral mean in iron sulfate?
The roman numeral indicates the number of electrons iron lost because its a metal it always wants to lose electrons thus making it a cation. Ex. iron (II) ---> Fe^+2
The difference between a positive and a negative charged atom?
First, if it is charged it is called an 'ion' and if it is positively charged it has lost one or more electrons from its outer parts and if it is negatively charged it has captured one or more electrons into its outer parts - as compared with its ground state which is when it has the same number of negative electrons in its outer parts as there are positively charged protons in its center and is therefore electrically neutral. all atoms are neutral, they have the same number of negatively charged electrons as they have positively charged protons (which is equal to the atomic number of that atom). metals can lose all of their valence electrons to get a complete outer orbital electron configuration, to form positively charged cations (+1, +2, and +3). They lose negatively charged electrons so they end up positive. ions are not atoms, they are atoms that have lost electrons or non-metals can gain electrons to fill their valence orbitals (becoming -1, -2, or -3). these nonmetals with extra electrons are anions, but anions are not atoms, they are atoms with extra electrons.
Typically atoms gain or lose electrons to achieve what?
Stable I think.
Why does roman numerals be in MnO 5?
Metals are oxidized, ie they lose electrons. An oxidized metal will bond with another element. The roman numerals signify how many electrons the metal lost which is called an oxidation number.
What is the maximum and minimum oxidation number of arsenic?
Arsenic is in group 15, it can lose 5 valence electrons or gain 3 valence electrons to achieve the octet. Its minimum oxidation state we can predict as being -3, and its maximum as +5
What does a metal atom need to do in oreder to form a cation?
lose 1 or more electrons
How does a cation form?
Cations form when atoms lose electrons, they gain a positive charge as a result.
How does an ion become a cation?
any atom lose one electron or more become positive ion ( Cation ) Dont really get your question:( BY definition, an atom that has lost or gained an electron meaning its a charged particle. A cation is an atom that has lost electrons to form a positively charged atom meaning that a cation is an ion. However, an anion also falls under the definition of an ion ( An anion is an atom that has gained an electron to form a negatively charged particle) In that case, it will need to lose electrons to form a cation(positively charged particle.) Not sure if you are referring to that though hope that helps:DD
Cations form when an atom gains electrons?
Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains electrons.
What is formed when atoms lose electrons?
A cation, which is a positively charged ion, is formed when an atom loses electrons.
How is a positive charge formed?
When an atom lose electrons become a cation (positively charged).
How is cation is form?
A cation is formed by the loss of an electron from the valence shell of an atom.
How many electrons can aluminum?
Aluminium lose 3 electrons and form the cation Al3+.
What is a cation and is it on the periodic table?
cation is positively charged ion. metals lose electrons to form cations.
How does a atom become an cation or an anion?
an atom becomes a cation when the atom loses electrons during a reaction, and it becomes an anion when the atom gains electrons in a reaction it accepts an additional electron.
What form when atoms lose or gain electrons and become positively or negatively charged?
If you are asking what it is called, when an atom looses or gains electrons it is called an ion. Electrons are negative, so when an atom looses electrons it becomes more positive and is called an cation. So, when an atom gains electrons it becomes more negative and is called an anion.
How do you write the formula of a cation?
A cation is a positively charged particle that is attracted to a negative cathode. Cations are formed when an atom loses an electron to have a full outer shell. Metals usually lose electrons to form a cation. They have a positive charge because the atom now has more protons (positive) than electrons (negative). Example Na+, Mg2+ , Al3+ Heather (N Ireland)
