It's chromium. The element would have lost 2 electrons from the 4s subshell, leaving 3d4 as your valence.

How many 3d electrons are in arsenic element?
The 3d subshell is completely filled in Arsenic. Therefore it has 10 electrons.
What element has 2 electrons in the 1s sublevel and 4 electrons in the 2s level?
An element cannot have 4 electrons in the 2 s level. The s subshell can hold only TWO electrons. Carbon has 4 electrons in the 2p level, however, if that's what you meant.
What type of element is characterized by the presence of electrons in the d orbitals?
All transition metals have valence electrons in a d-orbital.
Silver atom has completely filled d-orbitas in its ground state but how can you say that it is transition element?
According to definition, transition elements are those which have partially filled d-subshell in there elementary state or in one of the oxidation states. silver(z=47) can exhibit 2 oxidation state in which it has incompletely filled d-subshell (4d9). hence silver is regarded as trnsition element.
What is the transition element with 25 electrons?
Manganese, Mn is a transition element with Atomic number 25 and thus 25 electrons.
Name an element with electrons in the f subshell?
Terbium Tb
What element that is a transition element with 25 electrons?
Manganese
What is the most electronegative element and why?
Fluorine (F) is the most electronegative element because it has 5 electrons in it's 2p subshell. The optimal electron configuration of the 2p subshell has 6 electrons. Since F is close to this optimal configuration, electrons are highly attracted to the nucleus.
Is carbon transition element?
Carbon is group 14 element and comes under p-block elements. It is because its last electrons fall into the p-subshell. Its electronic configuration is 1s22s22p2 . Transition elements are the elements of d-block.They are named so because their position in the Periodic Table lies between the s-block and p-block elements. They have their last electrons filled in the d-orbital.
What is a transition element with 30 electrons?
ZINC, of course
How many 3d electrons are in arsenic element?
The 3d subshell is completely filled in Arsenic. Therefore it has 10 electrons.
How many electron in subshell of vanadium element?
The electrons per shell in vanadium: 2, 8, 11, 2.
What element on the periodic table has ninety electrons?
A transition element of f-block Thorium has 90 electrons in natural state, it is a Radioactive element.
How can one element have more than one number of valencies?
Paired electrons in one of the subshell become unpaired and are promoted to higher subshell to create more than one valencies.
What is it meant by a transition element?
A transition element are those element who have a partially filled d or f subshell in any common oxidation state. It is also any set of metallic elements occupying a central block in the periodic table such as copper, iron, manganese, and chromium.
What element has 2 electrons in the 1s sublevel and 4 electrons in the 2s level?
