How many half filled orbitals are in the selenium atom?
Selenium has four half-filled orbitals - the 4s, 4p_x, 4p_y, and 4p_z orbitals. This is because selenium has four electrons in its 4th energy level.
How many half-fiiled orbitals are in a bromine atom?
A bromine atom has 7 half-filled orbitals: one in the 4s orbital, three in the 4p orbitals, and three in the 4d orbitals.
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
Why is helium atomic number 2?
Helium has an atomic number of 2 because it has 2 protons in its nucleus. Atomic number corresponds to the number of protons in an atom, which determines its chemical properties and its place in the periodic table.
How many orbitals are completely filled in an atom of an element whose atomic number is 19?
Three completely filled orbitals.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p6 3s1?
There are two completely filled orbitals in this atom: the 1s orbital with 2 electrons and the 2p orbitals with 6 electrons. The 2s orbital and 3s orbital are not completely filled.
Is helium considered a complete atom?
Yes it is, as it has completely filled s orbitals.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p3?
There are two orbitals that are completely filled in this atom: the 1s orbital with 2 electrons (1s2) and the 2s orbital with 2 electrons (2s2). The 2p orbital is not completely filled, as it should have a total of 6 electrons (2p6).
Is argon a reactive atom?
No. argon is chemically unreactive due to the presence of completely filled orbitals.
How many orbitals completely filled in an atom whose wlectron configuration is 1s2 2s2 2p6 3s1?
That would be 1s2, 2s2, 2p6 are the 3 orbitals that are completely filled. The other one is not filled because it only has 1 configuration. Hopefully this help....if not I apologize. *PUMA #4*
How many orbitals are completely filled in an atom of chromium?
In an atom of chromium, there are a total of 24 electrons, leading to a fully filled 3s orbital (2 electrons) and a fully filled 3p orbital (6 electrons). The 3d orbital would have 5 completely filled orbitals since it can hold a maximum of 10 electrons.
What do atoms of less reactivity tend to have?
For one, the atom's outer circle is completely filled with the maximum number of electrons - it's valence orbitals are filled.
How many orbitals are filled in a silicon atom?
In a silicon atom, there are four filled orbitals. Specifically, there are two filled in the 1s orbital and two filled in the 2s orbital.
What is the result of sodium atom transferring an electron to a chlorine atom and they become stable?
The result is what you use to put in the food. Table salt (or sodium chlorine). It's a very stable compound, as each of the ions have their orbitals completely filled. Recall that in their normal states, Sodium has only one valence electron, and the Clorine is missing one to have its orbitals filled.
Why is a helium atom stable with only two electrons in its outermost energy level?
helium has completely filled valence orbitals and hence is stable
How many half filled orbitals are in a arsenic atom?
Arsenic has three electrons occupying the three 4p orbitals in its valence shell. Hund's first rule tells us that they will each occupy separate orbitals before they start to pair up. So there are three half-filled orbitals in an arsenic atom.
