How is an elements position on the periodic table used to understand its properties and predict the type of bond it will likely form when combined with another element?
Ionic BondingElements can combine with other elements by ionic bonding, in which one atom gains one or more electrons, forming a negatively charged ion, and the other atom loses one or more electrons, forming a positively charged ion. The oppositely charged ions combine by means of electrostatic attraction to form an ionic compound.Covalent BondingElements combine to form molecules by means of covalent bonding, in which the atoms of both elements share electrons in a covalent bond.
How did Mendeleev predict the properties of silicon?
Mendeleev did not predict the properties of silicon.
Can meteorologists predict volcanoes?
The fact of whether or not geologists can measure or predict a valcano is silly each valcano is different and it is of nature thus there is not way to predict what it will do and when it will do it.
What is bohr model of the atom?
The Bohr model of the atom is based on four fundamental postulates. Although he did not claim to explain or prove these postulates, Bohr found that by applying them, he could predict the properties of single-electron atoms and ions to an amazing degree of accuracy. Using the Bohr model, it is possible to accurately predict the energy levels of all one-electron atoms and ions, such as H, He+, Li2+ Be3+, B4+, C5+, etc.The four key postulates of Bohr's theory are:1) Atoms have well-defined electron orbits.2) Atoms do not radiate.3) Electrons travel in circular orbits with specific angular momenta, and only certain values are possible (angular momentum is quantized).4) As electrons go from one orbit to the next, energy is either absorbed or released by the atom.The quantized angular momentum can be written as:I = n * (h/2*pi)where I is the angular momentum, n is any integer, h is Planck's constant, and pi is the number pi, or 3.14159.See Web Links and Related QuestionsSee the Related Questions and Web Links to the left for the answer. Overview of the Bohr ModelNiels Bohr proposed the Bohr Model of the Atom in 1915. Because the Bohr Model is a modification of the earlier Rutherford Model, some people call Bohr's Model the Rutherford-Bohr Model. The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. Unlike earlier models, the Bohr Model explains the Rydberg formula for the spectral emission lines of atomic hydrogen. The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar). The gravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively-charged nucleus and the negatively-charged electrons.Main Points of the Bohr ModelElectrons orbit the nucleus in orbits that have a set size and energy.The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.Radiation is absorbed or emitted when an electron moves from one orbit to another. Bohr Model of HydrogenThe simplest example of the Bohr Model is for the hydrogen atom (Z = 1) or for a hydrogen-like ion (Z > 1), in which a negatively-charged electron orbits a small positively-charged nucleus. Electromagnetic energy will be absorbed or emitted if an electron moves from one orbit to another. Only certain electron orbits are permitted. The radius of the possible orbits increases as n2, where n is the principal quantum number. The 3 → 2 transition produces the first line of the Balmer series. For hydrogen (Z = 1) this produces a photon having wavelength 656 nm (red light).Problems with the Bohr ModelIt violates the Heisenberg Uncertainty Principle because it considers electrons to have both a known radius and orbit.The Bohr Model provides an incorrect value for the ground state orbital angular momentum.It makes poor predictions regarding the spectra of larger atoms.It does not predict the relative intensities of spectral lines.The Bohr Model does not explain fine structure and hyperfine structure in spectral lines.It does not explain the Zeeman Effect.

How do you find if an element is anion or a cation?
An element's number of protons can predict whether it will form a cation or anion. It will form a cation if it has more protons than electrons, or an anion if there are more electrons than protons.
How do you read the electrostatic series?
The electrostatic series ranks elements in order of their ability to gain or lose electrons. The list shows which elements have a higher affinity for electrons (indicating electron gain) and which have a lower affinity (indicating electron loss). This ranking can help predict the direction of electron transfer in chemical reactions.
What is the negatively charged particle that is one of the three building blocks of atoms?
That's the electron, located outside the nucleus. Electrons swirl about in a cloud around the nucleus, this cloud is somewhat organized into shells but is impossible to predict the place of one electron at anytime.
What is motivational patterns?
Motivational patterns are considered to be a series of things that follow a particular sequence which influence something positively. This can be traced and used to predict future patterns.
What is the negatively charged particle that is one of the three basic building blocks of atoms?
This is the particle in an orbital in the space around the atoms nucleus and it is called an electron.
How can you predict an atoms approximate weight if you know its atomic number?
The atomic number is the number of protons or electrons in an atom (there are the same amount of protons and electrons in an atom unless it's positively or negatively charged). The atomic weight is the average weight of the protons or electrons plus the neutrons of all the different isotopes of the atom. That's one of the reasons why the atomic weight of each element on the table of elements is not an integer. If you multiply the atomic number by two, you'll have a fair estimate of the atomic weight for the top part of the periodic table. For the heavier elements, this will come up a little bit light.

What are the people that predict things for insurance companies?
An actuary is a highly skilled mathematician who helps to calculate the rate that needs to be charged by the insurer based upon the likelihood that an event will occur. The premium charged by the insurer to the consumer is a function of the rate.
Predict what would happen if you touched the knob of a positively charged electroscope with another positively charged object?
In order to test the presence of a charge on an object, the object is brought near to an uncharged pith ball. If the object is charged, the ball will be attracted to it and move toward it. The attraction occurs because of induced polarisation of the atoms inside the pith ball. The pith is a nonconductor, so the electrons in the ball are bound to atoms of the pith and are not free to leave the atoms and move about in the ball, but they can move a little within the atoms. If, for example, a positively charged object is brought near the pith ball, the negative electrons in each atom will be attracted and move slightly toward the side of the atom nearer the object. The positively charged nuclei will be repelled and will move slightly away. Since the negative charges in the pith ball are now nearer the object than the positive charges, their attraction is greater than the repulsion of the positive charges, resulting in a net attractive force. This separation of charge is microscopic, but since there are so many atoms, the tiny forces add up to a large enough force to move a light pith ball. source: http://en.wikipedia.org/wiki/Electroscope
