well you see, 1s2 2s2 2p6 3s2 3p6 3d5 4s2 is manganese if it becomes 2+ then it loses 4s2 first so it would now look like 1s2 2s2 2p6 3s2 3p6 3d5 which is manganese 2+ but has the spdf of vanadium
hope im helpful
When an atom is no longer neutral and has gained or lost electrons, it is called an ion. An atom that has gained electrons will have a negative charge (an anion), while an atom that has lost electrons will have a positive charge (a cation).
Oh, dude, aluminum loses electrons like it's trying to shed some weight before summer. It's all like, "See ya, electrons, I don't need you weighing me down." So yeah, aluminum loses electrons to become positively charged because it's all about that positive energy, you know?
metals lose electrons to form ions so as to obtain noble gas configuration. for e.g. sodium(Na) has 11 electrons i.e. 1 electron in its valent (last) shell, to attain noble gas configuration sodium loses 1 electron which may be gained by a non-metal to stabilize itself.
No. Ions are formed by the loss or gain of electrons. the mass of electrons is negligible when compared to the mass of the nucleus (or the atom). Hence ions have the same mass as that of the atom of the element.
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
surely i don't know sodium atom which can be gained 2 electrons but anyway i thought the answer is Na+2
You can determine how many electrons are gained or lost by looking at the atom's charge. If the atom gains electrons, it becomes negatively charged; if it loses electrons, it becomes positively charged. The difference between the atom's original and final charge tells you how many electrons were gained or lost.
some are made losing lots of yams did you know that

We know what we know because we have gained knowledge. Knowledge is gained from going to school and through reading books.

I know but like pls
If an element gains electrons, it has a negative oxidation number. The oxidation number is determined based on the number of electrons gained or lost by an atom in a compound. The rule is that in ionic compounds, the oxidation number of an element is equal to the charge it would have if it were an ion.

An electron is the subatomic particle that has a negative charge.A proton has a positive charge and neutron has a neutral charge.These three together form all known particles (except hydrogen, that doesn't normally have a neutron). The protons and neutrons form the nuclie. The electrons form shells around it, they are held in place by there attration to the protons. Ions are atoms that have lost or gained electrons. e.g.[Zn]+1is a zinc alom that has gaind an electron.
Generally an atom has equal number of electrons and protons. and we know that electrons are negatively charged and protons are positively charged so atom is neutral. But when an atom loses electrons it acquires a positive charge. And this positive species is called cation.
