Ionization energy = the amount of energy it takes for an atom to lose an electron
Remember that the nucleus is positively charged and the electrons are negatively charged. Because those opposite charges attract, the nucleus is pulling the electron towards it and so, the closer an electron is to the nucleus of an atom, the stronger it is being pulled.
Now remember that as more electrons are added to match the number of protons, the shells fill up and each new shell that is made to accommodate for the electrons is further away from the nucleus. That means that the more electrons are in an atom, the more shells there are, and as the shells get further away from the nucleus, the electrons in those shells are pulled with much less force than electrons in the closer shells.
Now all that's left to remember is that as you go down the groups, the elements have bigger numbers of protons and so they have more electrons and so more shells.
Ta da!! Hope that helps!! :D
Where do we pick or where is it
Answer:
b
Explanation:
by using formula
a=(v-u)/t
where a= acceleration
v = initial velocity = 10 m/s
u= final velocity =50 m/s
t = time taken = 2s
Solar panels ( Solar-powered photovoltaic )
The energy units that are necessary for a jump up or that are released in a drop down are called ENERGY PHOTONS.
An atom of an element is made up of many energy levels and electrons move among these energy levels continuously. The lowest possible energy level is called the ground state and for an electron to move from a ground state to an higher energy level energy is needed. When an electron move from an higher level to a lower level energy is released. These energies are called energy photons.
