Which statement about the nucleus is correct?

Which statement about the nucleus is correct?

Which statement about the atomic nucleus is correct? The nucleus is made of protons and neutrons and has a positive charge. Atoms have an equal number of protons, which each have a charge of +1, and electrons, which each have a charge of -1.

What is true about 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 statement correctly describes the shells surrounding the nucleus?

Which statement correctly describes the “shells” surrounding the nucleus of the atom? They account for the negative charge and most of the volume of the atom.

Which statement about an elements atomic mass is correct?

Which statement about an element’s average atomic mass is correct? it is weighted average, so common isotopes have a greater effect than uncommon ones.

At what atomic number do nuclei become unstable?

All other stable nuclei have a higher neutron-to-proton ratio, which increases steadily to about 1.5 for the heaviest nuclei. Regardless of the number of neutrons, however, all elements with Z > 83 are unstable and radioactive.

What makes the nucleus of an atom positively charged?

The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

What is the function of nucleus in an atom?

An atom nucleus is made up of protons and neutrons. Protons bear a positive charge equal to the electrons orbiting around, and the neutrons bear no charge but weigh the same as the protons. Q: What is the function of an atom’s nucleus? The atom nucleus creates the force required to keep the atom together and in order.

Which statement best describes the nucleus of an Aluminium atom?

Which statement best describes the nucleus of an aluminum atom? It has the a charge of +13 and is surrounded by a total of 13 electrons. What is the charge and mass of a proton?

Which particles occupy the orbitals surrounding the nucleus?

Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
