What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3?
arsenic
This is our answer, so the element act should be arsenic.
What are the valence electrons for copper?
Copper (Cu) has two valences Cu I (cuprous) has one valence electron and Cu II (cupric) has two valence electrons.
Why the valency of copper is 1 or 2?
Copper has valency ‘1’ and ‘2’ that is the number of electrons lost or gained is 1 or 2 in different compounds.. For C u C l CuCl CuCl the valency is one as it needs one chlorine atom for this compound, hence its name is cuprous chloride.
How many valence electrons does Co2+ have?

How many valence electrons does Cu2+ have?
Here, the electron configuration of copper ion(Cu2+) is 1s2 2s2 2p6 3s2 3p6 3d9. This electron configuration shows that the copper ion has three shells and the last shell has seventeen electrons. In this case, the valence electrons of the copper ion(Cu2+) are seventeen.
What is copper valency 1 called?
Cupric
Cupric is the name of copper having it’s valency 1 . Cupric is the name of copper having it’s valency 1 .
Why does copper have a +2 charge?
Copper (II) ions have a 2+ charge. This happens when copper atoms lose two electrons, Its formula is Cu2+.
Does Co2 have 16 valence electrons?
Carbon dioxide’s formula is CO2 . Each carbon atom has 4 valence electrons and each oxygen has 6 valence electrons. 4 + (2)(6) = 16 valence electrons.
What is the electronic configuration of Co2?
Electronic configuration of Co+2 is [Ar]3d7.
Is Co2+ a cation or anion?
Cobalt(2+) is a divalent metal cation, a cobalt cation and a monoatomic dication. It has a role as a cofactor.
Why Co2+ is more stable and Co3+ is highly unstable in aqueous solution?
Solution : Adding the two half reaction, EMF comes out to +ve. This means that Co(III) in aqueous solution has the tendency to change to Co(II). Hence, Co (III) is not stable in aqueous solution.
What element is 1s2 2s2 2p6 3s2 3p6 3d2?
Which of the following elements has the electron configuration 1s2 2s2 2p6 3s2 3p5?

What is electronic configuration of Cu2+?
The electronic configuration of Cu II is 3d9, whereas that of Cu I is 3d10.
Does copper have 1 or 11 valence electrons?
Yes, copper only has 1 valence electron. Remember: valence electrons only include the electrons in the highest energy (n) shell.
What is copper with valency 2 called?
Answer. Explanation: Copper (Cu) has two valences Cu I (cuprous) has one valence electron and Cu II (cupric) has two valence electrons.
Why does copper only have 1 valence electron?
The valence shell of Cu is fourth shell. Thus its valence electrons are present in 4s,4p sub shells. Thus total number of valence electrons is 1.
