What is the most electronegative element?
fluorine
Thus, fluorine is the most electronegative element, while francium is one of the least electronegative. (Helium, neon, and argon are not listed in the Pauling electronegativity scale, although in the Allred-Rochow scale, helium has the highest electronegativity.)
How can you determine the behavior of elements?
Atomic number An element and its place within the periodic table are derived from this concept. When an atom is generally electrically neutral, the atomic number will equal the number of electrons in the atom, which can be found around the core. These electrons mainly determine the chemical behaviour of an atom.
What is an unpaired electron called?
● Atoms with unpaired ↑ electrons are called paramagnetic. ● Atoms with paired ↑↓ electrons are called diamagnetic.
What element has two unpaired electrons in energy level?
Ni has two unpaired electrons in its 3d orbitals. In the buildup of atoms, electrons occupy the 4f orbitals before the 6s orbitals.
What is atom and explain their behavior?
An atom is about the same size as a molecule: The protons and neutrons in an atom are concentrated in the atom’s center. The atom is mostly empty space. The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom.
Is oxygen a paramagnetic?
Due to the presence of two unpaired electrons, we can say that the oxygen molecule is paramagnetic in nature. The reason why oxygen is paramagnetic is because of the presence of two unpaired electrons.
What orbital is dumbbell?
p orbital
The s orbital is a spherical shape. The p orbital is a dumbbell shape.
Are helium electrons unpaired?
The only answer choice without unpaired electrons in its ground state is helium. Recall from the chapter that a diamagnetic substance is identified by the lack of unpaired electrons in its shell.
Is carbon paramagnetic or diamagnetic?
We have unpaired electrons here for carbon when we draw out the orbital notation. And unpaired electrons means that carbon is paramagnetic. So carbon is paramagnetic.
