Answer:

The general trend is for ionisation energies to increase across a period. In the whole of period 2, the outer electrons are in 2-level orbitals - 2s or 2p. ... That causes greater attraction between the nucleus and the electrons and so increases the ionisation energies.

The amount of substance present in a certain object with a given half-life in terms of h can be expressed through the equation,

A(t) = (A(o))(0.5)^(t/h)

where A(t) is the amount of substance after t years and A(o) is the original amount. In this item we are given that A(t)/A(o) is equal to 0.89. Substituting the known values,

0.89 = (0.5)(t / 5730 years)

The value of t from the equation is 963.34 years.

<em>Answer: 963 years</em>

Goryan [66]

The electronegativity of nitrogen (N) is 3.0, while the electronegativity of hydrogen (H) is 2.1. As it can be seen that nitrogen (N) is more electronegative than that of hydrogen (H),

So electron pairs are attracted towards nitrogen and thus it carries a partial negative charge and hydrogen carries a partial positive charge. The image of electron distribution is attached as follows.

Thus NH₃ is a polar molecule .
