Question

50. Question The atom of an element X contains 17 protons, 17 electrons and 18 neutrons whereas the atom of an element Y contains 11 protons, 11 electrons and 12 neutrons. (a) What type of ion will be formed by an atom of element X? Write the symbol of ion formed. (b) What will be the number of (i) protons (ii) electrons, and (iii) neutrons, in the ion formed from X? (c) What type of ion will be formed by an atom of element Y? Write the symbol of ion formed. (d) What will be the number of (i) protons (ii) electrons, and (iii) neutrons, in the ion formed from Y?​

Answer 1

Step-by-step explanation:

a) If an atom of element X loses one electron, it will form a positively charged ion or cation with the symbol X^+.

b) (i) 17 protons, (ii) 16 electrons, (iii) 18 neutrons.

c) If an atom of element Y gains one electron, it will form a negatively charged ion or anion with the symbol Y^-.

d) (i) 11 protons, (ii) 12 electrons, (iii) 12 neutrons.

Answer 2

An atom of element X forms an ion by gaining one electron, resulting in the symbol X-. An atom of element Y forms an ion by losing one electron, resulting in the symbol Y+. The number of protons, electrons, and neutrons in the ions formed from X and Y can be determined using the given information.

Step-by-step explanation:

(a) An atom of element X, with 17 protons and 17 electrons, will form an ion by gaining 1 electron. This results in an ion with 18 electrons. The symbol for this ion is X-.
(b) The number of protons, electrons, and neutrons in the ion formed from X will be: (i) 17 protons, (ii) 18 electrons, and (iii) 18 neutrons.
(c) An atom of element Y, with 11 protons and 11 electrons, will form an ion by losing 1 electron. This results in an ion with 10 electrons. The symbol for this ion is Y+.
(d) The number of protons, electrons, and neutrons in the ion formed from Y will be: (i) 11 protons, (ii) 10 electrons, and (iii) 12 neutrons.
