How does the number of protons compare to the number of electrons in a canton

Tema [17]

Answer: The number of protons in cation is more than the number of electrons

Explanation:

cations are positive ions that means that they lose electrons to be stable nd have electron configuration (atomic number ) equivalent to the preceding noble gas

as : sodium 11 , it loses on electron to be stable and its electron configuration is equivalent to neon 10

so ,the number of protons in cation is more than the number of electrons

i hope it helps!

I'd really appreciate help- this is due in around 8 hours :"D

Fed [463]

Answer:

atomic #= 1

protons equals one
Number of neutrons equals to 0
number of electrons equal to 1
mass number equals to 1

atomic number equals to 1
Protons equals to 1
number of neutrons equals to 0
number of electrons equals to 0 because the plus sign means that it loses an electron
mass number equals to 1

atomic number 17
number of protons 17
number of neutrons 18
number for electrons 18 Because negative sign means It's an anion which means it gains an electron
mass number 35
