What charge is on an ion with 35 protons and 38 electrons?
By definition, every atom of every element must have the same number of protons as every atom of that same element. So, all you have to do is find which element has 35 protons. Look at the periodic table, and find the 35th listed element. That element is Bromine. So Bromine is the correct answer.
Why must the number of protons always stay the same in an atom?
if the number of protons changed, the atom would become a different element
Neutral atom of a certain element has 15 electrons?
What is element 15? If it's the element on the periodic table with the atomic number 15, it would be Phosphorus which does have electrons, 15 of them. All elements on the periodic table have electrons.
How many protons does the magnesium cation have?
The periodic table states that the atomic number of magnesium is 12. A magnesium atom would thus have 12 protons in its nucleus; any atom that has 12 protons must be a magnesium atom. Atomic number = number of protons
How do you determine the number of protons in the nucleus?
The number of protons in an atom determines the chemical identity of that atom. (And only that, by the way.) We use the atomic number to state the exact number of protons in all atoms of a given element. Hydrogen has the atomic number 1 because every atom of hydrogen has exactly one proton. Also, every atom with exactly one proton is hydrogen. Helium is atomic number 2, and the same thing applies. All helium atoms have exactly 2 protons, and all atoms with exactly 2 protons are helium atoms. To determine the number of protons in a given atom, look at which element it is and find it on the periodic table or on a list of the elements. Then find its atomic number, which will be the exact number of protons in every atom of that element.
What part of an atom must change for the atom to become a new element?
An atom must gain or lose protons from its nucleus to become an atom of another element. The number of protons, and to a much lesser extent the number of neutrons, will determine the chemical properties of an element.
How many protons are in an atom of a pure element?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.

If an atom has 16 protons that atom must be which element?
Sulfur, which atomic number (in the PS) is 16, by definition equal to the number of protons in the nucleus
Neutral atom of a certain element has 15 electrons?
What is element 15? If it's the element on the periodic table with the atomic number 15, it would be Phosphorus which does have electrons, 15 of them. All elements on the periodic table have electrons.
Is a atom an element?
An atom is an element. Every atom has a certain amount of protons, neutrons and electrons and these are what define which element that atom is.
How many protons does the magnesium cation have?
The periodic table states that the atomic number of magnesium is 12. A magnesium atom would thus have 12 protons in its nucleus; any atom that has 12 protons must be a magnesium atom. Atomic number = number of protons
Why must there be a balance of protons to electrons in a element?
They have opposite charges, and an atom should be neutral.

Which two subatomic particles are present in equal number in every atom of the same?
In each neutral atom of any given element, the numbers of electrons and protons are equal, as the charges in the atom must balance. Only the neutron number may vary amongst atoms of the same element.
What atom has 5 protons and 6 neutrons and 5 electrons?
I'm almost positive the protons always tell you the identification of an element on the periodic chart... the atom with 6 protons is Carbon a non metal but if electrons are 5 then it must be carbon cation C+.
