How do you make a 3d model of an helium atom?
Building a helium atom model is one of the more simple projects kids and parents will face for school. A helium atom contains two protons, two neutrons and two electrons. The nucleus of a helium atom consists of the protons and neutrons. This will be the four center Styrofoam(TM) or foam craft balls in the model. The electrons will be the two outer balls that are stationed on the rings. To build the helium atom model pictured you will need the following supplies mentioned in this article. http://www.associatedcontent.com/article/1046660/how_to_build_a_helium_atom_model.html?cat=58
How can you make a 3d model of a lithium atom?
lithium atom is just a ball it has 1s and 2s orbitals both of which are spheres the 1s is occupied by two electrons and the 2s one electron
What is the best description of Bohr model of the atom?
Each electron in an atom is in an orbital (*NOT* an orbit!!) at a specific energy level from the positive nucleus. The energy levels of these orbitals are fixed -- an electron can go from orbital 's' to orbital 'p', but it can't go halfway between these two orbitals. When an electron in an atom goes from a higher orbital to a lower one, then the atom must give off an amount of energy, that is exactly the difference in energy in the two levels. For a hydrogen atom, these orbital levels are fixed by the fact that the angular momentum of an electron in an orbital is quantized -- ie, it comes in exact multiples, but not fractions, of a minimal amount.
What is Niels Bohr's quantum model of the atom also known as?
It is known as the planetary model, because he envisioned small scale atomic structure to be analogous to large scale astronomical structure. However, the two are based on separate forces : the atom on the strong force, and the universe mainly on gravity.
Bohr model atom?
they will always have two valence electrons
Identify the correct formula for a compound with one calcium atom and two fluorine atoms?
CaF2
What is used identify an atom?
Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.

Identify two problems that may occur when preparing soft meringues?
Weeping and beading.
What two firms identify with similar problems but from different countries?
China and the united states
What are the social or environmental problems in sandton?
identify and discuss two social and two environmental issues in sandton city
Identify two different ways that a single atom might produce a magnetic field?
Imagine a hydrogen atom with one orbiting electron. The electron that is orbiting would generate two magnetic fields. One caused by its rotation, and the other caused by its spin.
What is a detailed explanation of the electron cloud model?
Scientist use the electron cloud model to represent an atom.In the electron cloud model, an atom has two distinct regions-the nucleus and the electron cloud.

What are the differences between the plum pudding and planetary models of the atom?
The plum pudding model describes the atom as a pudding, occupying most of the volume an atom occupies. The pudding is positively charged. Inside the large pudding are negatively charged specs (plums), representing electrons. This model was found to be flawed because, when alpha particles were fired at atoms, it was found that a proportion of the positively charged alpha particles consisting of two neutrons and two protons backscattered. This meant that the positive charge density (charge per unit volume) of the atom must have been greater than what was described by the plum pudding model. For this to make sense, most of the atom must actually have been a vacuum. Therefore, the planetary model was created to describe atom more accurately. In the planetary model (nuclear model), the atom consists of electrons orbiting a nucleus. The nucleus consists of protons and neutrons.

What are two features of the modern model of the atom?
energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.
