The atomic number of an atom is equivalent to which of the following?
The atomic number of an atom is equivalent to the number of protons in its nucleus.
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
What is the expected hybridization of the central atom of ICl3?
In icl3 central atom is iodine and its valency is 7 out of 7 electrons 3 electrons are in chemical bonding so 2 lone pairs are there. Hybridization = number of sigma bonds + number of lone pairs = 3 sigma bonds + 2 lone pairs = 5 = sp3d ( 1 s + 3 P + 1 d = 5 ).
What is an atom's atomic number best described as?
The number of protons in the atom's nulceus.
What do you get if you subtract the atomic number from the mass number for a particular atom?
mass no - atomic no = number of neutrons in an atom.
How many have sp3 hybridization on the central atom out of SiCl4 BrF5 AsF5 BrF3?
1
What is the geometry of methanol?
It has a tetrahedral structure: there are three atoms of hydrogen attached to the central atom (carbon) as well as an oxygen. There are no lone pairs on the carbon. This will result in a steric number of 4.
Which electron-pair geometry corresponds to a steric number of 4?
steric number of an atom(for example the N of NH4) within a compound is calculated by adding up the number of atoms bonded to that atom(H's bonded to the N) plus the number of lone electron pairs (in this case none, because N's 2p shell is now full, rendering it a stable molecule). This gives NH4 a steric number of four. The positive charge comes from the additonal H+
The letter A in a VSEPR formula represents the?
The A represents the central atomand always has an implied subscript one.The X represents the number of sigma bonds between the central atoms and outside atoms. Multiple covalent bonds (double, triple, etc) count as one X.The E represents the number of lone electron pairs surrounding the central atom. The sum of X and E, known as the steric number, is also associated with the total number of hybridized orbitals used by valence bond theory.
What is steric interference?
When an atom comes too close to another atom, their electron clouds overlap and repel, this state is unfavorable and is characterized by higher energy.
What is the molecular shape of IO3?
Linear. It actually exists as I3- meaning that one of the iodines has an extra electron. Putting the extra electron at the central iodine atom gives you two bond pairs and three lone pairs, for a steric number of 5. Linear. It actually exists as I3- meaning that one of the iodines has an extra electron. Putting the extra electron at the central iodine atom gives you two bond pairs and three lone pairs, for a steric number of 5.
What determine the molecule geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
What determines the molecular geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
What is the number of nonbonding electron pairs on the central atom of NH2Cl?
4
What is the number of lone pairs around the central atom and the molecular geometry of scl2?
angular with 109.5 degree
Determine the number of electron groups around the central atom for H2S?
It has 4
What is the hybridization of the central atom H2O?
In H2O, the central atom is Oxygen atom and it is sp3 hybridised
