3. Ions in the same group tend to form ions with the same​

Chemistry
1 answer:
kolezko [41]2 years ago
4 0

Answer:

Same charge.

Explanation:

Ions in the same group tend to form ions with the same charge. Elements belong to the same group on the periodic table form ions with the same charge because they have the same number of valence electrons. For example, all members of alkali metals have different number of shells but same number of electrons in their outermost shell so due to same number of outermost shell these alkali metals will make bonding with halogens which is a seven group that have seven electrons and needs one electron for attaining stability and forming ions on both atoms.

Which scientist arranged the elements in order of increasing atomic number, rather than increasing atomic mass?
pentagon [3]

Answer:

Henry Moseley

Explanation:

Dmitry Mendeleef and Lothar Meyer proposed a periodic table based on the atomic mass.

They stated a periodic law expressed as "chemical properties of elements are a periodic function of their atomic weights".

But, Henry Moseley in 1900s re-stated periodic law by changing the basis of the law from atomic weight to atomic number.

The present periodic law is stated as "the properties of elements are a periodic function of their atomic number".

A 10.0 ml portion of 0.010 m hcl is diluted by adding it to100.0 ml of water. what is the ph of the solution
Volgvan

From the calculation, the pH of the solution after dilution is 3.

<h3>What is the pH?</h3>

The pH is the hydrogen ion concentration of the solution. Now we know that;

C1 =  0.010 m

V1 = 10.0 ml

V2 = 10.0 ml + 100.0 ml = 110 ml

C2 = ?

C1V1 = C2V2

C2 = C1V1 /V2

C2 =  0.010 m  * 10.0 ml / 110 ml

C2 = 0.00091 M

pH = -log[0.00091 M]

pH = 3
