Why do element have a number of spectral lines?
Elements have a number of spectral lines because of the number of energy levels and electrons. An electron falling from n=2 to n=1 gives one line, and if it falls from n=3 to n=1, it gives yet another line, and so on.
What is Lewis notation?
Lewis structures (also known as Lewis dot diagrams, electron dot diagrams, and electron dot structures) are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently-bonded molecule, as well as coordination compounds. The Lewis structure was named after Gilbert Newton Lewis, who introduced it in his 1916 article The Atom and the Molecule. They are similar to electron dot diagrams in that the valence electrons in lone pairs are represented as dots, but they also contain lines to represent shared pairs in a chemical bond (single, double, triple, etc.). Lewis structures show each atom and its position in the structure of the molecule using its chemical symbol. Lines are drawn between atoms that are bonded to one another (pairs of dots can be used instead of lines). Excess electrons that form lone pairs are represented as pairs of dots, and are placed next to the atoms. Although many of the elements react by gaining, losing or sharing electrons until they have achieved a valence shell electron configuration with a full octet (8) of electrons, there are many noteworthy exceptions to the 'octet rule'. One example is hydrogen (H), which has only a single valence electron and tends to react to attain either 0 or 2 valence electrons. When H has two electrons in its valence shell, it could be said to obey a 'duet rule', and achieves a valence shell electron configuration equivalent to helium (He).
Are victors a measure of the friction on an object?
No, vectors are a measurement of speed in a specified direction. They can be represented by lines and arrows on paper, or as as numbers as in, "63mph at 127 degrees north azimuth."
Why magnetic strength is high at poles?
The answer is complicated. The simple answer is because the electron spin is aligned in the same direction. In most objects electron spin is random. In magnets most electrons are aligned with each other, creating a magnetic field. This orchestrated movement causes the field to be strongest at the poles.
How do you think the lines you observed in the hydrogen emission spectrum relate to the energy of the electrons in a hudrogen atom?
For a detailed explanation on the relation between spectrum lines electron energy check out avogadro.co.uk/light/bohr/spectra.htm
Do perpendicular lines have arrows at the end?
Yes because perpendicular line our made out of lines that go on forever so yah it has to have arrows
What type of graphics Icons arrows shapes and lines are considered?
Explanatory
How do you draw an array?
you use lines and arrows and draw through numbers
A what will move in the direction of the arrows on the electric field lines?
positive charge
What are the timing marks for a 2001 Chrysler PT Cruiser?
They are lines and arrows on the sprockets and engine.
What are some of the tools the kalinagos used?
they used nets,bows and arrows and fising lines
What do parallel universes look like?
lines that never end and are straight and have 2 arrows at the endParallel is 2 lines that can go on forever and never intersectEx:__________________________________
Electric field lines are drwan with arrows to show the directions of the force on an?
Test charge, I think is the answer you are looking for.
How do you find resulting point when point given reflects through 2 lines?
The points are Dependent. Just pot the points and put two arrows at the end of the lines.
What is Nitrogen's valence electron configuration?
When answering these questions just refer to the periodic table. Nitrogen is in the 5th column (excluding the d block) This means that Nitrogen has 5 valence or outer electrons (free electrons) I am assuming that you are referring to N2. NOTE we always want to achieve the stable 8 electron configuration but this cannot always happen. In the case of N2 this is possible since we have 2 N's therefore we have 2 x 5 electrons=10 we can have single double and triple bonds. single has 2 electrons double has 4 electrons triple has three therefore for each N to have 8 electrons (the stable number) :N(three lines)N: hence 2x2+3x2=10 so we are right this is the electron configuration.
What is the orbital diagram of iron?
Iodine's electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p5 Iodine's Nobel gas configuration is: [Kr] 4d10 5s2 5p5 Orbital notation is difficult to represent in this format, but would consist of one up and one down arrow on a single line for the 5s2 and for the 5p5 it would be 3 lines, the first two containing an up and down arrow and the last containing only one up arrow. Remember to place the arrows 1 1 1 before pairing (Hund's Rule) to keep your professor happy ;)
What is a line called with two arrows and two dots in the middle?
It is still a line (since lines are continuous, it has two arrows, one on each end of the line). The dots are used to name the line.it is called an number line
