An element with 148 neutrons in its nucleus is usually Gadolinium (Gd) with an atomic number of 64, as its Atomic Mass is approximately 157. There may be isotopes of other elements with 148 neutrons as well.
The nucleus is made of protons, neutrons and electrons. These element move in and out of the nucleus depending on the external environment.
Although the number of protons in the nuclei of the atoms of an element is constant, the number of neutrons varies in general. For instance, hydrogen comes in three forms, known as isotopes, one with no neutrons in its nucleus, one with one neutron and one isotope with two neutrons in its nucleus.
The main difference between isotopes of the same element is the number of neutrons in the nucleus. Isotopes have the same number of protons and electrons but different numbers of neutrons, which affects their atomic mass.
An atom's mass number is the total number of protons and neutrons in its nucleus. It is used to identify isotopes of an element since isotopes of the same element have the same number of protons but different numbers of neutrons.
The synthetic element with 148 neutrons and named after a country is Americium. It was named after America, where it was first synthesized in 1944. Americium is commonly used in smoke detectors and has various industrial applications.

There are a couple elements who could have isotopes with 148 neutrons. The most stable isotopes of both americium and plutonium have 148 neutrons.
All neutrons (of all elements) are located in the nucleus (as all ptotons are)
The element with 135 neutrons in its nucleus is Xenon, which has an atomic number of 54.
All elements have neutrons and protons within the nucleus.
Neutrons are found in the atomic nucleus of an element, along with protons. They have no electrical charge and help stabilize the nucleus. The number of neutrons in an element can vary, leading to different isotopes.

The smallest unit that shows the properties of an element is an atom, and yes, an atom has protons and neutrons in the nucleus.
Ruthenium typically has 102 neutrons in its nucleus.
An atom with a nucleus that has no neutrons is hydrogen-1, which consists of one proton and no neutrons. It is the simplest and lightest element on the periodic table.
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
