How many electrons are in the scandium valence shell?
The element scandium has 21 electrons. However, most of these occupy the inner orbitals. The only electrons in the valence shell are those in the 2s orbital. Since there are two such electrons, scandium has 2 valence electrons.
State the Octet rule?
The octet rule states that:Each atom in a chemical compound gains, looses, or shares electrons to form octet (8) electrons in their highest occupied energy level.They completely fill up the s and p orbitals.Also in a covalent bond, it achieves a more stable noble gas configuration.
Which element has the same number of valence electrons as As?
Sb (antimony)
Why the oxidation states vary in a periodic but remains almost constant in a group?
Because within a group, the elements all have the same number of valence electrons, so their "combining power" (oxidation number) is relatively the same. In a period, the number of valence electrons increases going left to right, so the "combining power" changes.
What is duplet rule in chemistry?
According to the Lewis concept, "when two atoms form a covalent bond between them, each of the atoms attains the stable configuration of the nearest inert gas, by completing its "octet" or 8 electrons in the outermost shell, or " duplet" or 2 electrons in the case of hydrogen." In other words, the duplet rule states that when an element gets 2 electrons in its valence or last shell it has achieved a stable electronic configuration . The octet rule states that when an element acquires 8 electrons in the valence shell it becomes stable like the noble gases. Certain elements like lithium and hydrogen do not attain eight electrons in their outermost valence shell.
Do the halogens have different numbers of valence electrons?
no, but lower halogens have different oxidation states.
How many electrons are in the scandium valence shell?
The element scandium has 21 electrons. However, most of these occupy the inner orbitals. The only electrons in the valence shell are those in the 2s orbital. Since there are two such electrons, scandium has 2 valence electrons.
What element is likely to follow the duet rule?
You probably mean the octet rule, which states that atoms undergo chemical bonding in order to achieve an octet (8) of electrons in their valence shell. This makes them stable. All of the main group elements follow this rule, except for hydrogen. It is stable with two valence electrons. The main group elements are Groups 1, 2, and 13-18.
What does the number of the group or family on the Periodic table states?
Number of group indicates valence electrons. There are 18 groups.
What are the metals called in groups 3 through 12?
They are called the transition metals. They sometimes have multiple valence states, which makes predicting how they react tricky. Often their symbol is accompanied by a Roman numeral, which simply tells you their number of valence electrons. For example, Cu(II) means copper with 2 valence electrons.
Why would a hydrogen attach to chlorine?
Hydrogen has one valence electron. To form a compound, it must follow the octet rule, which states that the total outermost orbital (valence) contains eight electrons. The Chlorine atom contains seven valence electrons. H(1) + Cl(7) = 8 (follows the octet rule)
What rule states that to be stable atoms need 2 valence electrons?
This rule doesn't exist; you think probable to octet rule.
How is that an element can have many forms if the protons never change?
Different number of neutrons result in different isotopes:Hydrogen - 1 proton, no neutronsDeuterium - 1 proton, 1 neutronTritium - 1 proton, 2 neutrons (radioactive)Different oxidation states by exchanging electrons between higher energy "hidden" orbitals and valence orbitals:Ferrous - Iron with 2 electrons in valence orbitalsFerric - Iron with 3 electrons in valence orbitals

How many unpaired electrons in the ground state of neon?
There are 0 unpaired electrons which would make it diamagnetic
What rule says atoms need to have 8 valence electrons?
All atoms want to have their outer energy levels full. When they have eight valence electrons they are full. They will become full by combining with other elements that the they may encounter until they see eight. You also could say until they have eight valence electrons.
The octet rule indicates that?
In chemistry, the octet rule states that an atom has eight electrons in its outer shell. When all eight electron orbitals are filled, the atom is described as non-reactive. Examples include neon and argon.
