Answer» Answer: i) No. of neutrons = Mass no. - No. of protons = 35 - 17 = 18 ii) No. of electrons in an orbit = 2n², where n is the orbit number iii) The isotope of zX^A is zY^A+M, where z is the no. of protons and A is mass no. and M is GENERALLY a SMALL POSITIVE integer (In isotopes no. of protons are same but mass no. varies, like H¹,H²,H³) iv) False, ATOMIC no. 11 is of Sodium(Na) which forms unipositive cation. Elements like Aluminum(Al) having atomic number 13 forms tripositive cation. HOPE this will help you

Answer:

i) No. of neutrons = Mass no. - No. of protons = 35 - 17 = 18

ii) No. of electrons in an orbit = 2n², where n is the orbit number

iii) The isotope of zX^A is zY^A+M, where z is the no. of protons and A is mass no. and M is GENERALLY a SMALL POSITIVE integer (In isotopes no. of protons are same but mass no. varies, like H¹,H²,H³)

iv) False, ATOMIC no. 11 is of Sodium(Na) which forms unipositive cation. Elements like Aluminum(Al) having atomic number 13 forms tripositive cation.
