Question

Atoms are known to form charges due to their ability to gain and lose electrons in reactions. As a result, atoms become ions that are positively or negatively charged depending on the loss or gain of electrons. Which of the following atoms has a charge of +1 given the number of electrons?
a
Se: 36 electrons
b
S: 18 electrons
c
Na: 10 electrons
d
Cl: 18 electrons

Answer 1

Answer: C. Na: 10 electrons

Explanation:

Na (Sodium) has an atomic number of 11 and usually has 11 electrons. If it loses one of those electrons, it will have one more positively charged proton than it does negatively charged electrons giving it a +1 charge.

Answer 2

Answer:

C

Explanation:

Na has an electron configuration of 2,8,1

it forms an ion by losing 1 electron thus gaining a 1+ charge
