Answer:
Na⁺
Explanation:
Given parameters:
Number of protons = 11
Number of neutrons = 12
Writing the expression based on sodium ion that lost one electron;
In a neutral sodium atom, the number of protons and electrons are the same. Number of protons are the the positively charged particles in an atom.
Number of electrons are the negatively charged particles.
If an atom loses electron for instance sodium:
Number of electrons = 10
Number of protons = 11
Charge on the atom = 11 - 10 = 1+
So, the symbol of the atom is Na⁺
The answer to this question would most definitely be the last one
There are a couple of ways in which you can express the concentration of a solution, and here they are: gram per liter (g/L), molarity (M), parts per million (ppm.), and percents (%).
As you can see, only M appears in your answers, which means that the correct option should be (2) 3.5 M.
The will be c. Covalent bond and
Newton's third law of motion states that for every action force, there is an equal and opposite reaction force so that means that the wall is pushing you with the same amount of force that you put on it.
