Do particles pop in and out of existence?
Yes! Particles and atoms and ever larger assemblages of atoms. All this is a consequence of quantum mechanics.
How can scientist observe atoms?
By using a telliscope
The half-life of Au-198 is 2.7 days When there are 800 atoms of Au-198 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 8.1 days there are atoms of Au-198 re?
its 100
can a scientist see atoms?
They can't see atoms with a naked eye, but they can use an electron microscope or a STM (scanning tunneling microscope).
What scientist discovered that atoms have energy level?
The scientist who discovered that atoms have an energy level is Niels Bohr in 1913. According to his model electrons move around the nucleus much the same as the planets rotate around the sun.
What is the modern description of the electrons in atoms?
There are two main models used today one being the bohr model and then there's the quantum mechanical modal
Which model of the atom shows electrons traveling around the nucleus in wave patterns?
The Bohr Model, and its the basis of quantum theory
Molecular orbital theory is based upon which model of the atom?
Molecular orbital theory determines molecular structure that the electrons are not assigned as individual bonds between atoms, however, are treated as moving under the influence of the nuclei in the whole molecule.
Is it possible to use your model to predict which individual atoms will decay during one half-life?
radioactivity is a quantum mechanical statistical process. it is impossible to predict what any specific atom will do.
What causes atoms to behave the way they do?
Quantum Mechanics
Why have scientist developed models for the structure atoms?
To make them easier to understand. To make it possible to visualize the atoms and understand what they're actually doing. It helps to understand how they interact with each other and how they interact with other things.

How do you determine location of an electrons atoms?
use the quantum theory
What were atoms and how do they behave?
Atoms are things that make up elements and compounds Their behaviour varies depending on their state. Atoms in solids vibrate but don't move around Atoms in liquids move around but stick together. Gas particles are very free and they shoot about in the air
Names and symbols of the four quantum numbers required to define the energy of electrons in atoms?
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
What is the name of the scientist who discovered that atoms have positive charged?
Ernest Rutherford is the name of the scientist who discovered that atoms have positively charged nuclei.
What is the force that hold atoms together in a covalent bond?
Covalent bonds are held together by electrostatic (+/-) attractions between the nucleus of one atom and electrons from another atom and vice versa and there is also a quantum mechanical effect of delocalisation.
