If a sodium ion (Na+) has a positive charge and loses an electron when combined with chlorine, will the sodium atom become a new element? Why or why not?

No

Explanation:

loss of electron doesn't affect the element.

only change in proton number can, as we notice in nuclear chemistry.

please mark brainliest

just did the assignment and the answer was #1 +2 n

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
