What else can I help you with?
Of the metals Pb Hg Na and Mg which will not spontaneously donate electrons to copper in solution?
Lead (Pb) and Mercury (Hg) will not spontaneously donate electrons to copper in solution because they are lower in the reactivity series than copper. Sodium (Na) and Magnesium (Mg) are more reactive than copper and could potentially donate electrons to copper in solution.
Can you find out the number of electrons by adding protons and neutrons?
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
How would you describe an atom in which the number of protons is equal to the number of electrons?
You could describe it as neutral as the charge of the protons cancels out the charge of the electrons, essentially though it is just a normal atom as if the number of protons was different to the number of electrons, it would be classed as an ion.
Does the atomic number equal the amount of neutrons?
no, the atomic number, for the most part, is how much protons and electrons there are. The number of neutrons is determined when you subtract the atomic number from the atomic mass. When chemical bonding happens however, the number of electrons and protons could differ.
If you only know the number of electrons can you determine the element?
No; not if it is an ion. A chlorine atom, for example, has 17 protons and 17 electrons, but a chlorine ion (like when it is in sodium chloride, which is table salt) has 17 protons and 18 electrons. So, if you see an element with 18 electrons, it could be a chlorine ion, an argon atom, or a potassium ion.

At n 1 the total number of electrons that could be found is?
At energy level n=1, the total number of electrons that could be found is 2, as the first energy level can hold a maximum of 2 electrons.
What can be rounded to 50000 45000 and 45300 what is the least number it can be what is the largest number it could be?
your answer is least 45250 largest is 45299
What is the largest number that could round 800?
849
What is th largest number ever?
There is no such thing. As soon as you find the "largest number" you could just add one and it would be bigger. Again and again forever.
How many electrons can an atom hold in its outermost level?
The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.
In an atom the number of what is equal to?
In an atom the number of electrons is equal to the number of protons. That is, in the case of an un-ionized, non valence bonded molecule... If the atom were ionized, it could have fewer or less electrons. If the atom were part of a valence bonded molecule, it could be sharing valence electrons with other atoms.
What is the largest decimal number you could make using a number in the thousandths place?
0.9999

What could the piano do that the keyboard could not do?

What does the atomic number determmine?
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
