Imagine you are about to investigate what happens when sodium and potassium are mixed together. Before you begin your experiment
inessss [21]

Explanation:

Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.

For a compound to form two elements must combine in a definite order to given  single product.

The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.

Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.

73.5 mol of P4O10 contains how many moles of P ? moles of P:
Sholpan [36]

Answer:

294 moles of P

Explanation:

For every 1 mol of P4O10 contains 4 mol of P

so;

73.5 mol P4O10 × <u> </u><u> </u><u> </u><u> </u><u> </u><u>4 mol P</u><u> </u><u> </u><u> </u><u> </u><u> </u>

1 mol P4O10

= 73.5 × 4

= 294 moles of P

Light elements with an atomic number less than 20 generally have a neutron to proton ratio equal to
Natalija [7]
Atomic elements consist of a nucleus that contains protons and neutrons. Protons carry a positive charge whilst neutrons are electrically neutral. In light elements with an atomic number less than 20, the neutron to proton ratio is generally equal to 1:1. This changes for heavier elements since the Coulomb interaction between many protons gets stronger and demands more neutrons for the nucleus to remain stable.

In 1869 he published a table of the elements organized by increasing atomic mass.

Mendeleev is called the "father of the modern periodic table

stated that if the atomic weight of an element caused it to be placed in the wrong group, then the weight must be wrong. (He corrected the atomic masses of Be, In, and U)

was so confident in his table that he used it to predict the physical properties of three elements that were yet unknown.

After the discovery of these unknown elements between 1874 and 1885, and the fact that Mendeleev's predictions for Sc, Ga, and Ge were amazingly close to the actual values, his table was generally accepted.

However, in spite of Mendeleev's great achievement, problems arose when new elements were discovered and more accurate atomic weights determined.
