Answer:

Option c, Each element has its own neutron number

Explanation:

Atomic number of any element is unique. All the atoms of an element have the same atomic number. Atomic number defines the identity of the element.

Atomic number is equal to number of proton. So, number of proton is also unique or each element has its own number of proton.

Chemical symbols are used to represent element in easiest way. Therefore, chemical symbol has to be specific for each element.

Atoms of an element can have different number of neutrons. Atoms of an element having same no. of proton but different no. of neutron are called isotopes.

So, among the given option, option c is false.

How was the periodic law rearranged to become the periodic table, and what is its purpose?

alexandr402 [8]

Answer:

At earlier times elements were arrangrd on the basis of their atomic masses to study their properties easily but there were various problems like isotopes needs different position in perodic table.

After discovery of atomic number modern periodic table was created on the basis of atomic number (number of proton) that is unique for each element and varies regularly. So study of a group of elements is much easier than each element seperately that is why modern periodic table was formed.

Answer:

<u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Correct answer - C

Explanation:

A solid sodium metal reacts with gaseous form of chlorine gas to form a solid sodium chloride.

This formation of sodium chloride arises due to transfer of one valence electron from sodium to chlorine atom and the both atoms get stable octet electronic configuration.

As a result, an ionic compound solid sodium chloride is formed.

The chemical reaction of formation sodium chloride is as follows.

$2Na(s)+Cl_{2}(g) \rightarrow 2NaCl(s)$

Therefore, <u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.
