Answer:

Te

K

Explanation:

Main group elements are elements designated and located on the s-block and p-block on the periodic table. The core group or prominent elements are the elements that make up those groups. These groupings comprise the most naturally rich and abundant elements. The main group elements are those whose characteristics are more predicted as a function of their periodic table location. From the given options, only Te and K are elements of the main-group.

fgiga [73]

Answer:

Explanation:

The two carbon atoms would be different. These different carbon isotopes are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass number due to the difference in the number of neutrons in their various nuclei.

Carbon for example has 3 known isotopes which are:

                    ¹²₆C         ¹³₆C         ¹⁴₆C

These isotopes have different places in nature where they can be found. Some can occur together naturally.

Isotopes have the same chemical properties because they share similar electronic configuration.

Calculate the Molarity (M, moles solute / Liter of solution) of a solution that is made by dissolving 3.456 mmoles of Barium per
yan [13]
Since Molarity is moles per Liter, you will first need to convert the mL into L, which makes it 0.4321L. Next divide: moles on top, Liters on the bottom.
3.456 moles / .4321L = 7.998 M
