The valence electrons are the electrons in the outermost electron shell of an atom.
Explanation:
The number of electrons in an atom's outermost valence shell governs its bondingbehaviour.
That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table.
Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration <span><span>s2</span><span>p6</span></span>.
This tendency is called the octet rule, because the bonded atoms have eight valence electrons.

Answer:
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Explanation:
Based on the calculations, the acceleration of this block as it slides down from the friction less ramp is equal to 0.85 m/s².
<h3>How to determine the acceleration of the block?</h3>
In order to determine the acceleration of this block, we would apply Newton's Second Law of Motion while taking moment about the tensional force.
The vertical component of the tensional force that is acting on the block as it slides down from this friction less ramp is given by:
T = Ma - Mgsinθ
0 = Ma - Mgsinθ
Ma = Mgsinθ
a = gsinθ
Substituting the given parameters into the formula, we have;
a = 9.8 × sin25
a = 9.8 × 0.4226
Acceleration, a = 0.85 m/s².

Answer:
a) 13I₁ + 18I₂ = 30v
b) 18I₁ - 5I₃ = -12v
c) I₁ = I₂ + I₃
d) I₃ = I₁ - I₂
e) 5I₁ - 23I₂ = 24v
f) I₁ =2.88A
I₂ = -0.41A
g) I₃ = 3.29A
h) I₂ = 1.41A
The significance of the negative sign of I₂ is that the direction of the flow of current I₂ is opposite to the direction assumed.
