<em>Same group element have same</em><em><u> Valence electron</u></em><em> and behave similarly in </em><em><u>Chemistry.</u></em>

<u>Explanation:</u>

For example. First group elements Alkali metals:- H, Li, K, Rb, Cs, Fr

Valance electron will take part in forming a bond with other elements and compound will form. All the above-given elements (H-Fr) have valence electron 1 in outer most 'S' shell. All have electronic configuration S1

Behavior: Since valence electrons are the same so the behavior of all the elements in this group is the same. All are metal (from Li-Fr, except Hydrogen), all are very reactive, does not found in native state in the environment, and all react with water.

Determine the percent ionization of a 0.230 m solution of benzoic acid.
Fudgin [204]
We need the dissociation constant of benzoic acid which is 6.3x10^'5. Then using the dissociation formula, ka = x2 / (Mo - x) where Mo is the initial concentration. x is determined then. percent ionization is computed as (x/Mo)* 100%. This is then the final answer.

maksim [4K]
<h3>Answer:</h3>

Protons

<h3>Explanation:</h3>
  • An atom is the smallest particle of an element that can take part in a chemical reaction.
  • All atoms of the same element are similar in that they have the same number of protons.
  • Atoms of the same elements may have a different number of electrons or neutrons but will always have the same number of protons.
  • Atoms of the same elements with a different number of neutrons are known as isotopes.
  • When neutral atoms gain or lose electron(s) they form charged atoms known as ions.
