What happens to an electron during an electron transition?
Drops to a lower energy level and emits one photon of light.
An atom gives up an electron to form a positive ion?
yep
Does the flame of the gas stove give light of visible wavelength?
Certainly; you can see the light that it gives off.
A molecule that gives up an electron becomes both ionized and oxidized?
true
What is the atomic number for Ca?
the atomic number of Ca or calcium is 20. That gives it an electron arangement of 2,8,8,2, It has 20 protons and 20 electrons with a full valence electron shell. Hope this helps you
The de Broglie wavelength of an electron is 8.7 10-11 m The mass of an electron is 9.1 10-31 kg The velocity of this electron is ms?
wavelength = h/p (h= Plancks constant = 6.636*10^-34 kg*m^2/s) p=m*v Combining these gives us v=h/(m*wavelength)=8.37*10^6 m/s
What happens to an electron during an electron transition?
Drops to a lower energy level and emits one photon of light.
If wavelength is multiplied by frequency what is the answer?
Wavelength times frequency gives the speed of the wave.
What information does the first quantum number if an electron give?
The energy level an electron gives
What gives the atom its chemical properties?
the electron
When hydrogen electrons goes from n equals 3 to n equals 1 what happens?
When an electron goes from a higher state to a lower state, it gives up energy equal to the difference of energy levels of the two states. This energy is in the form of a photon. If it goes directly from n=3 to n=1, then 1 photon is emitted. If it transitions from n=3 to n=2, then from n=2 to n=1, two (2) photons are emitted. Energy level of n=3 for Hydrogen is -1.511 eV (electron volts) Energy level of n=2 for Hydrogen is -3.4 eV (electron volts) Energy level of n=3 for Hydrogen is -13.6 eV (electron volts) The energy levels are 'more negative' at lower levels because the electron becomes more bound to the atom. From n=3 to 1 (gives up 12.089 eV, or a photon with wavelength 102.518 nm - ultraviolet light) From n=3 to 2 (gives up 1.889 eV, or a photon with wavelength 656.112 nm - red light) From n=2 to 1 (gives up 10.2 eV, or a photon with wavelength 121.5 nm - ultraviolet) See related link post.
In ionic bonding the metal donates its valence electron to the?
The metal gives its electron(s) to a nonmetal.
Where on a wave diagram is the wavelength?
On a wave pattern, the measurement of distance between two corresponding wave peaks, troughs or crests will give the wavelength.
When an atom gives up an electron what is formed?
ions
Purely ionic bonds do not occur because the atoms that gives up an electron in such a bond?
purley ionic bonds do not occour because the atoms that gives up an electron in such a bond
What theory describes the wave properties of electrons?
When in motion, electrons (indeed, all sub-atomic particles) exhibit wave-like properties such a destructive and constructive interference. In the same way that EM radiation (ie, light) going through two slits will result in an interference pattern at a detector behind the two slits, electrons going through two slits will result in exactly the same kind of pattern -- even if the electrons go through the slits one at a time. The wavelength (λ) of a moving electron is given by λ = h/p where 'h' is Planck's Constant and 'p' is the electron's momentum. The calculation of the PROBABILITY of an electron, when within a specific energy field, being in a specific place is best calculated using the Schroendinger Equation. If you research this equation, you'll find two things: (1) it's an equation that gives results resembling a wave and (2) scientists still argue WHAT (if anyone) is actually waving. We still haven't decided if an electron's wavelength is a physical reality (like photons) or just a mathematical trick we use for simplicity.
What was your average wavelength when the waves had a 10cm amplitude?
There isn't any. The amplitude gives no information about the frequency or wavelength, and is completely unrelated to them.
