What else can I help you with?
There are two elements in the transition metal series rm Sc through rm Zn that have four unpaired electrons in their 2 plus ions?
Cr and Fe have four unpaired electrons in their 2 plus ions.
Ions with a 2 plus charge?
two elements with ions with a 2 plus charge are Sulfurand Oxygen
Is Mn2 plus cation?
Yes, Mn2+ is a cation. It has a charge of +2 because it has lost two electrons. Cations are positively charged ions formed by losing electrons.
How many ions does sulfur have?
69-
How many electrons will group 2a lose?
Group 2A elements typically lose 2 electrons when forming ions.
How many d electrons are present in Cr 2 plus?
It has 4 d electrons.
How many electrons in pb2 plus?
Pb2+ has lost two electrons, so it has 82 - 2 = 80 electrons.
When group A elements form ions they?
lose 2 electrons and form ions with a 2+ charge.
Is Zn 2 plus and Cu2 plus a isoelectronic specie?
Yes, Zn²⁺ and Cu²⁺ are isoelectronic species. Both ions have the same number of electrons, with Zn²⁺ having 30 electrons (atomic number 30, losing 2 electrons) and Cu²⁺ having 29 electrons (atomic number 29, losing 2 electrons). As a result, they both have the electron configuration of [Ar] 3d¹⁰, making them isoelectronic.
Why MgO exists only as Mg2 plus O2 but not as Mg plus O?
MgO exists as Mg2+ and O2- ions due to the difference in electronegativity between magnesium and oxygen. Magnesium readily loses two electrons to achieve a stable electron configuration, forming Mg2+ ions. Oxygen readily gains two electrons to achieve a stable electron configuration, forming O2- ions. This transfer of electrons results in an ionic bond between the magnesium and oxygen ions, rather than a covalent bond where electrons are shared.
How many electrons are in a beryllium cation Be 2 plus?
A beryllium atom (Be) has 4 electrons. When it forms a cation with a charge of +2 (Be²⁺), it loses two electrons. Therefore, a Be²⁺ cation has 2 electrons remaining.
How many electrons does a charbonate ion have?
actually there are 6 electrons in carbon and oxygen has 8 electrons and it gains 2 electrons to make it a negative ion so the total number of ions are 32
