The given formula for energy is:
(1)
where,
h = planck's constant
c = = (frequency)
n = energy level
Substitute the given value of n and in formula (1)
=
=
=
=
Thus, energy of an electron in the hydrogen atom when n = 5 is
a) Carbon and oxygen are chemically bonded in carbon dioxide.
The elements lose their individual identities in CO₂, and they always combine o the proportion C:O = 1:2.
You cannot separate the elements from each other by physical means.
Answer:
Lithium has 3 protons, 4 neutrons, 3 electrons, and its mass is 6.941 u
Answer:
C
Explanation:
You climbing the water slide gives you potential energy and your building gravitational eneergy.
The Lewis structure the student drew is incorrect. The total number of electrons in bonds and lone pairs is equal to the total number of valence electrons available, then a valid Lewis structure is produced.
The correct structure is the following:
The structure that was drawn by the student was incorrect because the total number of electrons around Oxygen were incorrect, there were 6 instead of 8, which was against the octet rule. The correct structure should have 8 electrons around each atom.
