The Atomic Number Of An Element Is

Posted on by



The atomic number of an element is the same as the number of protons in its nucleus. Each element has a unique number of protons that no other element can have, therefore it is used as an. According to the periodic table, which of these elements is a metal?. A.T B.Q C.X D.Z Element/ Number Of Protons T/ 7 Q/ 15 X/ 12 Z/ 17 (I. The atomic mass of an element is A. The sum of the protons and neutrons in one atom of the element. B. Twice the number of protons in one atom of the element. The atomic number (represented by the letter Z) of an element is the number of protons in the nucleus of each atom of that element.An atom can be classified as a particular element based solely on its atomic number. For example, any atom with an atomic number of 8 (its nucleus contains 8 protons) is an oxygen atom, and any atom with a different number of protons would be a.

.Q.The atomic number of an element is 17.
(a) Whether it is a metal or non – metal?
(b) Whether it is bigger or smaller in size than an element of atomic number 18?
(c) What is its valency?
(d) How would its oxide behave with litmus solution?
(e) What type of bonds it will form with element of group 18?
ANS :

(a) It is a non metal , atomic number 17 means it is a Halogen.

(b) It is Bigger than the element having atomic number 18 (along a period from left to right the size of atom decreases with increase in atomic Number)

(c) Atomic Number = 17

Electronic Configuration (EC) = 2 , 8 , 7

=> Valency = 8 - 7 = 1

The atomic number of an element is 56

(d) Its Oxide will be Acidic . It will turn Blue litmus into red ,thus indicating it is Acidic Oxide.

(e) Type of bond it will form with element of group 18 : Covalent bond (Non - polar Bond)

b) It will be bigger than the element of group 18.

c)Its valency is 1.

d)Its oxide will be acidic in nature and thus, it will turn blue litmus paper red.

What Determines Atomic Number

e) It will NOT form any type of bond with elements of group 18 as elements of group 18 are all noble gases and they are already stable substances and hence unreactive with any element..
