Does an atom always have the same number of neutrons and protons?

No. It is possible for one atom of an element to have a different number of neutrons than another atom of the same element. For example, H usually has no neutrons, but deuterium has 1 neutron. An atom with a different number of neutrons is called an isotope.

∙ 12y agoIf its 2 atoms that are the same type yes.
However if its 2 different type of atoms then no.
Different amounts of protons, neutrons and electrons in an atom change things completely.
***********2nd Opinion***********
I think the questioner was asking if the number of protons in an atom always equals the number of neutrons. The short answer is no. Some do, some don't.
***********3rd Opinion***********
Longer answer:
The number of protons in an atom determines the type of atom - the type of element. Some examples:
1 proton => hydrogen, 2 protons => helium, 3 protons => lithium ...
6 protons => carbon, 7 => nitrogen, 8 => oxygen, 9 => fluorine ...
13 => aluminum, 14 => silicon ... 26 => iron, 27 => cobalt, 28 => nickel ...
47 => silver ... 78 => platinum ... 79 => gold ...
The number of neutrons varies.
Atoms of the same element with a different number of neutrons are called isotopes, and may behave differently, [articularly in the context of nuclear fission or fusion and radiation.
Except for hydrogen and helium, all atoms have at least as many neutrons as protons.

∙ 12y agoYes, these are called isotopes of an element. For example the most common isotope of carbon is carbon 12, that is an atom with with 6 protons* and 6 neutrons. The next most common isotope of carbon is carbon 14, which has 8 neutrons instead.
Isotopes exist for all elements, but not all of them are stable. Carbon 14 happens to be radioactive.
*Theoretically atoms can have any number of protons and neutrons (but only o few will be stable). Only atoms made up of precisely 6 protons are carbon atoms.

∙ 14y agoAn atom of a specific element has allways the same number of protons but the number of neutrons is different for different isotopes of the element.

∙ 12y agoEvery atom has neutrons except for the most common isotope of hydrogen. 1H just has one proton in the nucleus.

What is the neutron and proton responsible for in an atom?
Protons make up the identity of the element and give it its unique properties. Protons have a positive charge. Neutrons give an atom additional mass, and the number of neutrons in an atom make it an isotope of an element. Neutrons have no charge.

What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
An equal number of protons and neutrons typically results in an atom that is?
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.

What does the atomic number of an atom made of?
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What particles make up the mass of an atom?
The number of protons
The number of protons and neutrons in an atom?
Depends on the atom. The atomic number will give you the number of protons. The atomic weight will give you approximately the number of protons and neutrons combined.
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
