Answer:
Explanation:
The nuclide isotope notation represents the isotope by its chemical symbol preceded by a superscript (to the left of the chemical symbol) showing the mass number and a subscript (also the the left of the chemical symbol) showing the atomic number (number of protons).
Copper-70:
Nuclide notation:
your answer is C. INDEPENDENT
because you can change an independent variable, but you cannot change a dependent variable.
hope this helps!
have a great rest of your day!
b . transition metal
c . inner transition metal
d . lanthanides-series element
Answer:
A - actinide-series element
Explanation:
If you go to the periodic table, the atomic number is 92. if you look for 92 you will end up in the inner transition metals then if you get more detail it would be in the actinide section.
The most specific classification for the element uranium is option a, it is an actinide series element. It is a radioactive element.
Uranium is 92nd element in periodic table. This is a f- block element. In periodic table the elements of groups 3-12 is called transition metals. Elements in f block is called inner transition elements.
The inner transition elements contain two classification, lanthanides and actinides. 57th to 71th elements are called lanthanides. 89 to 103 are called actinides.
Thus, uranium belongs to the actinide series of f block elements in the periodic table therefore, option a is correct.

The word that best fits is frequency. Thus,the sentence is,the frequency of a wave is a measure of the amount of energy it carries.
The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h frequency. So, the answer is frequency.
