An ionic bond is formed when there are more or less electrons that normal in bonding atoms.
<h3>What are Ionic bonds?</h3>
An ionic bond is formed when one atoms donates electrons to another specie to form an ion pair. One atom is positively charged while the other specie is negatively charged.
Hence, an ionic bond is formed when there are more or less electrons that normal in bonding atoms.

They are called representative elements.
Answer:
Explanation:
Given that;
diameter (d) = 10cm/2 = 0.1m/2 = 0.05 m
length (l) = 10 cm = 0.1 m
porosity = 50%
height (h) = 30 cm = 0.3 m
time (t) = 5 s
volume (v) = 60 cm³ = 60 × 10⁻⁶ m³
Q (flow rate) = 
Q = 
Q = 
From constant head method, we use the relation K = 
to determine the hydraulic conductivity ; we have:
Seepage velocity 
where; velocity = 
=
= 
To determine the mass of the sample, first find the volume difference after and before the aluminum was placed, the volume change is equal to the volume of the submerged object, in this case aluminum.
Then knowing volume of aluminum and the density of it, we can solve for the mass.
D = m/v
Dv = m
2.7 g/ml • 8 ml = 21.6 grams.
Atomic mass W = 183.84 u.m.a
1 mole --------- 183.84
1.4 moles ---- ?
1.4 x 183.84 / 1 = 257.376 g
hope this helps!
