Tropic levels have most energy
Answer: Option (5) is the correct answer.
Explanation:
It is known that the ground state electronic configuration of silicon is
.
And, we know that when an atom tends to gain an electron then it acquires a negative charge and when an atom tends to lose an electron then it acquires a positive charge.
As
has a +4 charge which means that it has lost 4 electrons. Hence, the electronic configuration of
is
.
According to the Aufbau principle, in the ground state of an atom or ion the electrons fill atomic orbitals of the lowest energy levels first, before filling the higher energy levels.
As 2p orbital is filled after the filling of 2s orbital.
Therefore, we can conclude that 2p orbital will be occupied by the electrons of highest energy for the
ground-state ion.
We are given with the mass of pure iron that reacts with oxygen to form an oxide which has a given mass as well. the mass of oxygen reacted is 8.15-6.25 g or 1.9 grams. THen we convert the mass of the reactants to moles. Iron is equal to 0.1119 moles and oxygen is equal to 0.1188. We divide each number to the less amount. Hence iron is 1 and oxygen is approx 1. The empirical formula hence is FeO or ferrous oxide or Iron (II) oxide.
Answer:
The statement is false. See the explanation below, please.
Explanation:
The hydrogen bond or bridge is a type of dipole-dipole interaction that is generated from the attraction of a hydrogen atom and a very electronegative atom (oxygen, fluorine or nitrogen). Examples of hydrogen bridge molecules: Water (H20), ammonia (NH3).
Its about 11.5hg because if you divide it with the atom it would result to 11.5hg
