Describe a stone falling off the tabletop in terms of both kinetic energy and potential energy?
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.
How much energy is available to first level consumers?
10%
What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.
What type if energy transfer when you eat a carrot?
Calories to jewls eventually. The calories have to be processed into fat and what not first, but then the muscles use them to create energy. So now you have it.
What is the energy conversion of a waterfall?
Dams
What is ionisation energy What is first ionisation energy?
The first ionization energy of an atom or molecule describes the amount of energy required to remove an electron from the atom or molecule in the gaseous state.
Why are the ionisation energy of isotopes the same?
no the same,first ionisation contains a slightly differences in isotopes
Why the first ionisation energy of potassium is only a little less than the ionisation energy of sodium?
both are in the same period which accounts for closeness. they are nonetheless different because there are more protons in the nucleus which means electrons are brought closer to it so there is a higher ionisation energy or potential
What happens to the first ionisation energy of the elements as a period is crossed?
tinger tinger tales
Which Lewis structure represent an atom x in period 4 with the highest first ionisation energy?
. .x ..
Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.
What are the ionisation enthalpies of potassium and sodium?
First ionization energy of sodium is 495,8 kJ/mol.First ionization energy of potassium is 418,8 kJ/mol.
What is the first ionization energy for sodium?
Na(g) --> Na+(g) + e- First ionisation energy is always: X(g) --> X+(g) + e- with X being an element
What is meant by the first ionisation energy of nitrogen?
THis is the energy required to remove(ionise) one (the first) outer most electron. For nitrogen this would be quite a large figure, because nitrogen, wants to accept electrons ,rather than remove electrons. As a general rule as you go along any given period, the ionisation energies increase. There are two 'humps', with a slight fall in ionisation energiers in this general increase.
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
Why the first ionisation energy of O is less than that of N?
oxygen is more electronegative and so it wants the electron more than N
Is fluorine ionization energy high medium or low?
first Ionisation energy is 1681 kJ/mol = 402.15 Kcal/mol it is high because of the F electron configuration will be 1s22s22p5
