What description best describes the nucleus of an atom?
The nucleus is a small, dense region at the center of the atom. It consists of positive protons and neutral neutrons, so it has an overall positive charge. The nucleus is just a tiny part of the atom, but it contains virtually all of the atom's mass.
Which of the following correctly describes the location of the particles in an atom?
Q. Which of the following best describes the locations of the three subatomic particles in atoms? Protons and neutrons are located in the cloud around the nucleus, and electrons are in the nucleus. Protons and electrons are located in the cloud around the nucleus, and neutrons are in the nucleus. Consequently, which statement correctly describes the location and charge of the neutrons in an atom? Which statement correctly describes the location and charge of neutrons in an atom? The neutrons are inside the nucleus and have a negative charge.
Then, what particle is most important in an atom?
I would say proton and electron are the two most important subatomic particles in an atom. The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world. What determines the reactivity of an atom? The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
How do protons identify the atom?
Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element. Since the atom is electrically neutral, the number of electrons must equal the number of protons. What determines the stability of an atom? An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom's nucleus may result from an excess of either neutrons or protons.
One may also ask what do neutrons determine about the atom?
The number of neutrons influences the element's mass; that is how isotopes of the same element differ.
- What do you mean by binding energy of a nucleus obtain an expression for binding energy how binding energy per nucleon explains the stability of nucleus?
- What is mantle description?
It set the stage for ground-breaking missions that extended humanity's reach across the solar system. NASA has flown more than 25 missions carrying a nuclear power system through a partnership with the Department of Energy.
- Where is the nucleus located in an atom?
A Mars solar day has a mean period of 24 hours 39 minutes 35.224 seconds and is referred to as a sol in order to distinguish it from the roughly 3% shorter solar day on Earth.
