Question

question 25 1 pts for sodium to transform from a neutral atom to a positive ion, it must: gain an electron. gain a proton. lose an electron. lose a proton. question 26 1 pts a weak acid: dissociates very little in solution. dissociates almost completely in solution. will cause the ph of the solution to rise above 7. does both b and c. question 27 1 pts the atomic number tells you the number of protons in the nucleus. number of neutrons in the nucleus. number of electrons. weight of the atom. question 28 1 pts

Explanation:

• Question 25: A neutral atom becomes a positive ion by losing an electron as electrons are negatively - charged. Losing one makes the atom have more protons than electrons, thus positive.
• Question 26: A weak acid dissociates very little in solution. Strong acids dissociate almost completely, and acids lower the pH of a solution (below 7), not raise it.
• Question 27: The atomic number of an element is defined as the number of protons in the nucleus of an atom of that element.

Answer:

• Question 25: C. lose an electron
• Question 26: A. dissociates very little in solution
• Question 27: A. number of protons in the nucleus
