This is how to get the look of a model...
1.Signature Color. First,have one color that your sure looks best on you.Have a neclace or something that color.Wear it with everything.That way,even when you have a dull looking shirt on or a old ripped sweat shirt,you'll still have at least something that still looks good on you!
2.Hair.Models are always changing there hair style.Try getting some tips from your favorite hairdresser.As styles change,you'll need the update on the newest,trendiest look!
3.Clothes.Even if you have clothes that are out of style,anyone can do the job that you need to.If your budget is tight,you can always add some glam to your look by adding rinestones to your tee or some sequines to you jeans.
4.Makeup.Out of all the steps leading up to getting picked at an addition,this may be the hardest.Today,girls can spend up to hundreds of dollars on makeup in 6 months.Theres an easy way to spend little money on makeup without emptying your wallet.This is what you need to do,by a large pallet of eyeshadow with at least 20 colors on it,a tube of mascara,a package of lip gloss,and a makeup bag to keep it all in.
A nuclear arms race combined with fear and suspicion could lead to a disastrous nuclear war.
The only technology Bohr needed to develop his model for the atom was a spectrometer, which, in the mid-1800s, revealed the emission lines of hydrogen. In 1885, Johann Balmer developed a mathematical formula (the Balmer Series) that fully described these lines, but nobody could explain why it worked.
Neils Bohr combined the quantum ideas of Max Planck and Albert Einstein with the atomic model proposed by Ernest Rutherford, and developed an atomic model from which the Balmer Series could be derived.
1. draw a circle and write in it 11 because that's its atomic number
2. because sodium is in the third period of the periodic table, draw 3 circles (shells) around the middle one
3. in the first shell draw two dots across representing electrons
4. next on the second shell draw 8 dots
5. on the third shell, draw 1 dot because the it is on group 1 of the periodic table
If you follow this format, you can do any element! You need to know the group, period, atomic number to do this, though.
Bohr's model provided a theoretical base to the Rydberg formula, but incorrectly involves the idea that electrons orbit the nucleus in circular paths. Schrodinger's equations, which are a model in themselves, fix this and "correctly" involves the idea that electrons are not actual particles with defined points when in an atom, but actually have regions of where they are most likely to be (for example, a 1s electron is 99% probably at the nucleus, whereas a 2p electron will be somewhere in one of two "bubbles" nearby) - the electrons in your body have an extremely small, but still possible, chance of all being in Jupiter right now - and allows us to calculate the properties and locations of these electrons.

The Bohr model suggests that electrons orbit the nucleus in circles and that these circles are all in a single plane.
They were caught the imagination of the public when in fact it was wrong.
It depends on what you mean by doctor. If you mean a medical physician, a medical degree such as the Doctor of Osteopathic Medicine (D.O.) or Doctor of Medicine degree (M.D.) are earned by American medical students. Internationally, the M.D. or Bachelor of Medicine/Bachelor of Surgery (MBBS/MBChB) is earned. If you mean a doctor in the research doctorate sense, that is a Doctor of Philosophy (Ph.D.).
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
quantam mechanics
It describes it because it is atom model and it had a nucelus, protoins and electrons
One possible answer is:
4, 1, -1, +1/2
Another possible solution is:
4, 1, 1, -1/2
The short answer is that Ernest Rutherford discovered the nucleus of the atom and was a mentor to Niels Bohr who further refined the model by showing that the nucleus was made up of neutrons and protons. The existence of electrons had already been inferred earlier. Ernest Rutherford opened the door to the field of nuclear physics whereas Niels Bohr's contributions pointed the way to quantum physics. At the time, it was noted that the nucleus within the atom takes up about as much space as a fly in a cathedral. Since then, it has been shown that the subatomic particles are themselves made up mostly of vast empty spaces containing tiny specs of something that may be described as either energy or matter or neither and both.
The electrons should get pulled into the nucleus of the atom by the attraction of the protons. There's also the problem that the electron should radiate energy away until it fell into the nucleus. Quantization is required to keep these things from happening.
Niels Henrik David Bohr was a Danish philosopher, scientific research promoter and a physicist that was born on October 7, 1885. He had a great contribution in atomic theory because he is the one who made the foundation contributions to understand the quantum theory and atomic structure, and because of that he received the 1922 Nobel Prize in Physics.
it has 28protons and 31 neutrons with 28 electrons and has 5 shells or orbitals. 2 in the first, 8 in the 2nd 3rd and 4th, and 2 in the fifth
Bohr's model explains how electron transitions cause hydrogen's atomic emission spectra. The quantum model is a 3-d view of the atom, which shows an electron's energy levels and sublevels and the probability of an electron's location, proven with complex mathematics.
Niels Bohr (the father, not the son who also got a Nobel prize) is known for:
- Nuclear models with layers explaining radiation
- Contributions to quantum mechanics
- Political work after WWII to put the nuclear bomb under UN control
