Describe the path electrons take in a simple flahlight circuit.
The amount of electrons it takes to make 80CU of charge would come as an equation. CU stands for Coulombs. It would take 4.9932078e+20 electrons for 80 CU of charge.
To make a positive ion, we need to remove one or more of the negative components from an atom. The negative charges that make up an atom are the electrons, which can be found in shells or orbitals some distance from the nucleus. Take away one or more electrons, and the protons, the positive charges that make up atoms and which hang out in the nucleus, give the atom an overall positive charge. An atom that has lost one or more electrons becomes a positive ion.
It takes 6.25E18 electrons to produce 1 coulomb of charge.
Metals give up electrons while non-metals gain electrons
Uranium is a donor of electrons.
give
No
phosphorus will accept 3 electrons or share 3 electrons
neon has completely filled orbitals, obeys octet and has stable electronic configuration. Hence it does not take or give electrons.
It gives away electrons.
Alkali metals GIVE electrons (the only one electron that they do have) so that they may become balanced.
Carbon's electronic configuration is-2,4 and hence it has 4 electrons in the outer most shell. Therefore it is highly difficult for it to give electrons and highly difficult for it to be stable after gaining an additional 4 electrons. But Carbon does give and also take electrons under certain favourable conditions.
Calcium atom will generally lose two electrons to form Ca2+ ions. Calcium will not accept (gain) electrons.
Nitrogen is a nonmetal with 5 valance electrons, which tends to receive three electrons to complete it outer electron shell.
