What else can I help you with?
Why must you arbitrarily use 90 percent of probability of finding an electron in the region?
The 90 percent probability is commonly used to define the boundaries of electron orbitals because it encompasses most of the electron's possible locations within a particular energy level. It provides a clear and practical way to visualize the regions where electrons are most likely to be found in an atom.
How did the predicted speed of movement compare to the actual speed of movement?
They matched within 0.001 percent.
Why does Li form covalent bond unlike other alkali which forms ionic bond?
Atomic number of Lithium is three. It has got two electrons in the first orbit. The third electron is free and in the outermost orbit. The atomic number of Sodium is 11 and that of potassium is 19. Sodium and potassium one electron in the outermost orbit. This outermost electron can be easily donated to have stable configuration. That is like Neon and Argon, respectively. So sodium and potassium can conveniently give up the last electron, rather than taking seven electrons to complete the outermost orbit. When sodium gives an electron, it loses about ten percent of charge. If potassium loses an electron, it loses about 5.5 percent charge. But if Lithium loses an electron, it loses 33.33 percent electrical charge. It will become grossly electrically positive in that case. Lithium feels uncomfortable to lose that much electrical charge. If Lithium forms the covalent bond, it does not have to become grossly electrically positive. Rather the electrical charge remains same, as the electrons are shared up in case of covalent bond. That is the reason as the why Lithium forms covalent bond, unlike other alkaline metals.
What is an electron orbital?
Orbital shapes are conic sections.A closed orbit is elliptical. That can include circular, but that's very unlikely, since the circleis just an ellipse whose foci happen to exactly coincide.An open orbit is hyperbolic. It can also be parabolic, but that's very unlikely, since the parabolais just the exact boundary condition between closed and open orbits.
Which part of the atom contains more than 99 percent of its mass?
The protons and neutrons found in the nucleus are responsible for the majority of the atom mass while the much smaller electrons orbit the nucleus.
Is it possible to have a 100 percent covalent bond?
No, it is not possible to have a 100 percent covalent bond. Covalent bonds involve the sharing of electrons between atoms, which means there is always some degree of electron sharing rather than a complete transfer of electrons. This sharing results in a partial overlap of electron clouds between the bonding atoms.
Over 99 percent of the mass of an atom is contained where?
Over 99% of the mass of an atom is contained in the nucleus, where protons and neutrons are located. Electrons, which have negligible mass compared to protons and neutrons, occupy the remaining space in the electron cloud surrounding the nucleus.
Is the location of an electron in an atom best represented by a probability cloud?
Yes, the location of an electron in an atom is best represented by a probability cloud, which shows the likelihood of finding the electron in a particular region of space. This concept arises from the wave-particle duality of electrons in quantum mechanics. The probability cloud provides a more accurate description of the electron's position compared to a classic model of electrons orbiting a nucleus in fixed paths.
What is the percent error if the predicted value is sixty eight and the actual value is eighty?

How can you use predicted in a sentence?
The weather prediction for today is cloudy with a slight chance of rain.The prediction of me getting a psp would be 55 percent.
What is the significance of drawing the ninety percent contour of orbitals?
Drawing the ninety percent contour of orbitals helps visualize the region in space where there is a high probability of finding an electron. The contour represents the volume encompassing 90% of the total electron probability density, giving insights into the shape and size of the orbital. This information is crucial in understanding chemical bonding and reactivity in molecules.

Can you felt a yarn that is 75 percent wool and 25 percent nylon i.e. crazy zauberball?
The resulting felt would not be as a pattern predicted that requires 100% wool. Nylon does not felt.
