Answer: 166.023×1023
Explanation:
Mass of 6.023×1023 atoms of oxygen = gram atomic mass of oxygen.
Mass of 6.023×1023 atoms of oxygen = 16g
∴ Mass of 1 atom of oxygen =166.023×1023
Z=35
- The element is bromine
- Sign(Br)
Electronic configuration:-
The positively charged particle of an atom is called Proton.
The negatively charged particle of an atom is called an electron.
When describing the velocity of an object, you must specify the both the speed and the direction.
That’s because <em>velocity is a vector</em>: it has both magnitude (speed) and direction.
If you say that a object is travelling southwest at 70 km/s, you are giving its velocity.
If you say that it is travelling at 70 km/s, you are giving its speed.
Because oxygen is more electronegative<span> than hydrogen. The oxygen atom in h2o pulls electrons towards itself, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. oppositely charfed ends of</span>water molecules<span> are attracted to each other, forming a hydrogen bond</span>
