Why do Ball stick models of atoms have different number of holes?
Wiki User
∙ 14y ago
The no. of holes that a ball stick model has is equal to an atom's no. of valence electrons, or the no. of bonds that it can form.

How do you Sift or Size Gravel?
The gravel is put into shakers with different size screens, with the screens with the larger holes on top. The gravel is then shaken, forcing the different sized rocks through the holes, which separates them according to size.
What is the definition of a classifier sieve?
Classifier Sieves are available in many different "Mesh" Sizes. These sizes are based on the holes per square inch. A size 8 would have 8 holes per square inch, and a size 20 would have 20 holes per square inch. These are used to separate different sizes of dirt from each other. Different types of prospecting equipment processes different mesh sizes of dirt.
Does gabbro have holes?

What animal lives in a tree hole in the rain forest?
One animal that lives in tree holes in the rainforest is the three-toed sloth. These slow-moving creatures spend most of their lives hanging upside down from tree branches and rely on tree holes for shelter and protection. They have long arms and strong claws that allow them to grip onto tree branches and move between different tree holes in search of food.
Do rocks usually have cracks or holes in them?

2 Describe the two commonly used molecular models?
Ball and Stick Models; In ball and stick models, the atoms are wooden of plastic balls with holes in them. Sticks or springs are used to represent chemical bonds. Each types of atom is represented by a specific color. and Space Filling Models; In this model, atoms are represented by truncated balls held together by snap fasteners so that the bonds are not visible. The balls are proportional in size to atoms.
How many holes are their in a tennis racket?
It it depends upon the string pattern. Different rackets have a different amount of cross strings and mainstrings, thus different number of holes.
Why are the guitar holes different to violin holes?
Different shape and size.
How rare are worm holes?
Current thinking has it that they don't exist. None have ever been observed, and most basic models of worm holes are unstable (they would collapse very quickly). There are some models which do allow for worm holes, but those models have not yet been accepted as true by most physicists; they are mainly models which ultimately aspire to become theories of everything and in order for worms holes to be stable they have to allow for certain exotic particles which are not currently part of the Standard Model of particle physics.
Are elements in all things?
No. An element is a group of the same kind of atoms. Compounds and mixtures contain different kinds of atoms, and thus, different kinds of elements.However, there are several things that are not made up of atoms. This includes light, different kinds energy, neutron stars, black holes... and the mysterious dark matter. The Universe contains at least 5 times as much dark matter, than atoms and other kinds of known matter.
