The correct statements from the given set of statements should be given. Concept introduction: The symbols of the elements in present in the periodic table are given by the first two letters of the name of the elements. The same electronic configuration containing elements are arranged in the same group in periodic table. The vertical columns of the periodic table are known as families. The elements present in the column are said to be of the same family. The transition metals having [n-1d 1 − 10 ns 2 ] electronic configurations While naming a covalent compound, the first element is named first followed by the naming of the second element. If the first element exhibits more than one oxidation state then the current oxidation state being exhibited is to be mentioned.

The correct statements from the given set of statements should be given.
Concept introduction:
The symbols of the elements in present in the periodic table are given by the first two letters of the name of the elements.
The same electronic configuration containing elements are arranged in the same group in periodic table. The vertical columns of the periodic table are known as families. The elements present in the column are said to be of the same family.
The transition metals having
[n-1d1−10ns2] electronic configurations
While naming a covalent compound, the first element is named first followed by the naming of the second element. If the first element exhibits more than one oxidation state then the current oxidation state being exhibited is to be mentioned.

Technetium is the first element in the periodic chart that does not have any stable isotopes.
Technetium-99m is an especially interesting and valuable isotope as it emits a gamma ray with a half
life ideally suited for medical tests. It would seem that the decay of technetium should fit the
treatment above with the result In(c/c) = -kt. The table below includes data from the two sites:

Graph the fraction (c/c.) on the vertical axis versus the time on the horizontal axis. Also
graph In(c/c.) on the vertical axis versus time on the horizontal axis.
When half of the original amount of starting material has hours fraction remaining
disappeared, c/c = ½ and the equation In(c/c.) = -kt becomes
In(0.5) = -kt1/2 where t₁₂ is the half life (the time for half of the
material to decay away). Determine the slope of your In(c/c.) vs
t graph and…
