What does a 3-d model of the molecular structure of californium look like?
Like the ball.
Does Kolbe formula represent a compound?
No, I had this as a choice in a check all that apply question and it is a junk answer meant to trip you up. The ways are structural formula,molecular formula,empirical formula,space-filling model,ball and stick model. Cheers.
What is the difference between a structural formula and a molecular model?
A chemical formula is the number of atoms in a substance, and is the same as a molecular formula (provided the substance is a molecule - if not, it has no molecular formula). A structural formula shows how the atoms are linked, and there are different interpretations of this: eg C3H8O2 is the chemical formula of 1,2 propan di-ol, which is the same as the chemical formula of 1,1 propan di-ol the structural formula however is CH2OHCHOHCH3 for 1,2 propan di-ol and CH(OH)2CH2CH3 for 1,1 propan di-ol. A displayed formula shows all the bonds: ........H..OH...H.............O-H...H...H ........|....|.....|..................|....|.....| ....H-C.-.C.-.C.-.H.....H-O-C.-.C.-.C.-.H ........|....|.....|..................|....|.....| ....H-O...H....H.................H...H....H 1,2 propan di-ol........1,1 propan di-ol ---------------------------------- Some chemicals, such as table salt, have no molecule. Thus, they only have chemical formula but not molecular formula. The chemical formula of table salt is NaCl. There are other salts, such as Na2SO4, MgSO4, etc. (If you hear people saying "the salt molecule has the formula of NaCl...", believe me, they do not know what they are talking about.) Some compounds exist as molecules- discrete entities, such as water. This kind of compounds have molecular formula. Water's is H2O. Structural formula? Never heard of.
What is ball and stick model?
The ball-and-stick model represents the bonds that hold the atoms together by using balls and sticks. The atoms being the balls and the bonds that hold the atoms together being the sticks. The bond length, the average distance between the nuclei of two bonded atoms, is 95.8 pm and the bond angle, the angle formed by two bonds to the same atom, is 104.45 degrees. (a) is a good example. The pink ball to the white ball is the bond length and the white ball to the other white ball is the bond angle.
What does the phrase sea of electrons mean?
A sea of electrons can be found in metals. The positive ions are arranged in fixed positions, while the electrons 'float' or 'wander' among the the positive ions. This makes metals good conductors of electricity. ----------------- Electrons of metals flow freely
What is vsepr model mainly used for?
The VSEPR model is used mainly to determine molecular shape.
What is the vsepr model mainly used for?
The VSEPR model is used mainly to determine molecular shape.
What model is used to determine molecular shape?
VSEPR model
Why is the VSEPR model mainly?
To determine molecular shape.
What is a visual model of molecular geometry?
VSEPR theory
Is the VSEPR mode a physical model a conceptual model?
VSEPR is a conceptual model, as it has not been directly observed.
The quantum mechanical model of bonding assumes that atomic orbitals overlap and produce?
molecular orbital
What is the difference between the Lewis model and the valence-shell electron pair repulsion (VSEPR) model?
VSEPR only shows the geometric shape of the element
What is the molecular geometry of OF2?
OF2 gemometry: sp3 hybridized atoms adopt a tetrahedral geometry. Becasue of the sp3 orbitals contain lone pairs, the VSEPR model indicates that the molecule has an overall bent geometry. The bond angles should be less than 109.5 degrees because the lone pairs repel each other more than the bonding pairs.
Is the molecular model of water the same molecular model as oxygen?
no. they are different
How does the VSERP formula explain molecular shape?
Valence electron pairs will move as far apart from each other as possible. (Apex)
What is the relationship between the VSEPR theory and molecular shape?
In this theory, electron pairs in the central atom repell one another and tend to space themselves as far apart as they can. This spacing on a 3 dimensional model gives rise to the various shapes of molecules.
