Sodium - Na is a neutral atom with 11 protons and 11 electrons.
protons are positively charged and electrons are negatively charged. Since the number of protons and electrons are equal, there are equal amounts of both positive and negative charges therefore they cancel out giving Na an overall neutral charge.
Na has 1 electron in the outermost energy shell, to become stable and to gain a noble gas configuration it loses the electron in its outermost shell.
Once it loses its electron, there are 11 protons and 10 electrons, having an overall positive charge of +1. Once atoms lose or gain electrons they become ions, since Na loses electrons its called a cation.
So in Na⁺, +1 stands for the net charge of the ion which is +1 or in other words Na has just lost one electron therefore is +1 positively charged
C. Im gonna say Proteins but I am not completely sure.
A positivey charged subatomic ion is a <em>proton</em> which is in the nucleus
A negitively charged subatomic ion is an electon which is found outside the nucleus in the electron cloud
A neutral subatomic ion is a <em>neutron </em>which is also in the nucleus
The concentration of the final solution will be 0.2886 M.
<h3>Molar concentration</h3>
50.6 g of NaCl is dissolved in 600 mL of water.
Mole of 50.6 g NaCl = 50.6/58.44 = 0.8658 mol
Molar concentration of the oiriginal solution = 0.8658/06 = 1.4431 M
25 mL of 1.4431 M of the solution is diluted up to the 125 mL mark.
m1 = 1.4431, v1 = 25 ml, v2 = 125 mL
m2 = m1v1/v2 = 1.4431 x 25/125 = 0.2886 M
The concentration of the final solution will be 0.2886 M
