What determines the relative sizes of the spheres in space-filling model?
In the space-filling model, what determines the relative sizes of the spheres? -the number of bonds -the type of atoms -the atomic radii -the bond length
What is the diameter of the largest sphere in space?
Diameter: For example, let us say the largest sphere was 21 cm in diameter. Jupiter is actually 142,000 km in diameter and Saturn is 120,000 km in diameter. So Saturn diameter is 18 cm.
How many atoms are there in a square sphere?
All 5 atoms lies in the same plane with the B atoms at the corners of a square and the A atom at the center of the sphere. Which shape could lead to a square-planar shape upon removal of one or more atoms?
What is relative size in psychology?
Relative size refers to the fact that the more distant an object, the smaller its image will be on the retina. Therefore, if there are two identical objects, the one that is farther away will be the one that has a smaller image on the retina.
What does a space-filling model show?
Space-filling models are useful because they show how much space an atom (or molecule) occupies. You can see this easily by comparing space-filling models with traditional ball-and-stick models like those in the following figure.
Why is space fill model used to represent compounds?
These particular models are classified as the space-filling type because they model the atoms as hard spheres that are in contact with one another. Although this is not an entirely realistic way to think about atoms, it provides a clear way of visualising the arrangement.
What are space filler diagrams in chemistry?
In chemistry, a space-filling model, also known as a calotte model, is a type of three-dimensional (3D) molecular model where the atoms are represented by spheres whose radii are proportional to the radii of the atoms and whose center-to-center distances are proportional to the distances between the atomic nuclei, all ...
What makes the ball-and-stick model different from the space-filling model?
The key difference between ball and stick and space filling model is that in the ball and stick model, the molecular structures are depicted by spheres and rods whereas, in the space-filling model, the molecular structures are depicted by full-sized spheres without rods.
What does the space-filling model of a water molecule tell you about the relative size of the atoms?
A space-filling model shows the relative amount of space each atom takes up. In other words, a space-filling model can show relative sizes of atoms. However, unlike ball-and-stick or structural models, space-filling models do not show bond lengths clearly. Bonds are not really like sticks in a ball-and-stick model.
Which of the following molecular models Emphasises the relative size of each atom based on its van der Waals radius?
The black ball of carbon is big
(iii) Space filing model:
These models emphasises the relative size of each atom based on its van der Waals radius.
What does each sphere in the molecular model represent?
In chemistry, the ball-and-stick model is a molecular model of a chemical substance which is to display both the three-dimensional position of the atoms and the bonds between them. The atoms are typically represented by spheres, connected by rods which represent the bonds.
How does ball-and-stick model work?
Ball and stick models are three-dimensional models where atoms are represented by spheres of different colors and bonds are represented by sticks between the spheres. Particular atoms are associated with different colors, for example, black is usually used to represent carbon and white to represent hydrogen.
What does a ball-and-stick model reveal about chemical bonds?
What do the sticks represent in a ball and stick model? In a ball and stick model, the sticks (rods) represent the bonds between atoms in a molecule. Furthermore, two and three more flexible and longer (curved) sticks are used to represent the double and triple bonds respectively.
How does the space-filling model of a molecule represent the sharing of electrons?
In a space-filling model, the overlapping parts of the spheres show where chemical bonds are formed in a molecule when electrons are shared. Scientists also use ball-and-stick models to show how the atoms in a molecule are connected to each other.
What factors determine the polarity of a molecule?
Polarity and Structure of Molecules The shape of a molecule and the polarity of its bonds determine the OVERALL POLARITY of that molecule. A molecule that contains polar bonds, might not have any overall polarity, depending upon its shape.
What is the significance of using the ball and stick to represent models of the series of hydrocarbons?
A ball and stick model can be used to show the structure of a simple molecule. This type of model has the advantage of showing how the atoms are connected and how they are arranged in space, including the angles between bonds.
