Answer:
Atoms.
They come together so they can form molecules (because of their electrons)
It becomes a covalent bond
Explanation:
The process that occurs at the anode in an
electrochemical cell is the loss of electrons. The answer is number 2. Oxidation occurs as electrons are lost at the
anode at one of the electrodes in both an electrolytic cell and a
voltaic cell.
Answer:
Answer is A: a uniform mixture that can’t be separated
Explanation:
Explanation:
Formula used for the radius of the orbit will be,
(in pm)
where,
= energy of orbit
= radius of orbit
n = number of orbit
Z = atomic number
a) The Bohr radius of an electron in the n = 3 orbit of a hydrogen atom.
Z = 1
476.1 pm is the Bohr radius of an electron in the n = 3 orbit of a hydrogen atom.
b) The energy (in J) of the atom in part (a)
is the energy of n = 3 orbit of a hydrogen atom.
c) The energy of an Li²⁺ ion when its electron is in the n = 3 orbit.
n = 3, Z = 3
is the energy of an Li²⁺ ion when its electron is in the n = 3 orbit.
d) The difference in answers is due to change value of Z in the formula which is am atomic number of the element..
Answer:
Okay so Carbon's is 6, then Neon is 10, Silicon is 14, and Barium is 56.
