Answer:
<h2>The answer is option A</h2>
Explanation:
To find out if the object sink or float in water we must first find the density of the object
From the question
mass of object = 2 g
volume = 4 mL
The density is
We have the answer as
0.5 g/mL
The object will float on water since it's density is less than that of water which is
1.0 g/mL
Hope this helps you
Explanation:
The electronic configuration of an atom can be represented by either sublevel notation or using shell notations.
Sublevel notations shows the sequence of filling electrons into the orbitals of the sublevels.
Shell notations are used to denote the electrons in all orbitals of each energy level.
Element Number of electrons Sub-level notation shell notation
