Below is a Bohr model of an element with 11 protons, 12 neutrons, and 11 electrons.

#16 Identify the symbol of the element. Be sure to write the symbol in proper format. *

#17 What is the mass number of the element? (Example: 35) *

#18 Write the electron configuration for this element. (Do not use the carrot ^ or commas , Example: 1s2 2s2 etc) *

#19 This Bohr model is representing an atom, not an ion. Explain how you would know. *

#20 If this atom were to lose one electron, would it become a cation or an anion? Explain. *

#21 Would the ionic radius of this element be larger or smaller than that of the atomic radius? Explain. *

Respuesta :

16. 11 protons means its atomic number is 11 so the element is ₁₁Na

17. mass number = sum of protons n neutrons = 11+12 = 23

18. 11 electrons means the configuration is 1s2 2s8 3s1

19. its an atom, not an ion cuz' no. of electrons = no. of protons so it is neutral n not charged

20. losing 1 e- will make Na +ve charge so it becomes a cation
