What occurs for two atoms to be isotopes of each other?
Two atoms are considered different isotopes of their element if they have different masses. This mass comes from the neutral-charged neutrons differing.
How are protons and neutrons different and alike?
Similarities1. They nearly have the same mass.2. They are both inside the nucleus. (They are both nucleons).3. Strong nuclear forces act on protons and neutrons.Differences1. Protons are positively charges and neutrons carry no charge.
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
How is an element with 56 protons and 82 neutrons related to an element with 56 protons and 78 neutrons?
They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
Does the nucleus of an atom have protons neutrons electron?
no, they don't. instead they make up the nucleus of the atom. protons and neutrons are made of quarks, which are held together by gluons.which means that the nuceuls and electrons together make the atom.
What are two ways that a proton and a neutron are similar?
Both protons and neutrons are of equal size and mass. However neutrons have no charge and protons have a positive charge. Neutrons are also used in beta radiation and can be changed into protons.
Is the difference between the mass number of an isotope and its atomic number is equal to the number of nucleons in the nucleus?
It is equal to the number of neutrons in the nucleus, not nucleons (which include both protons and neutrons.)
Why are protons and neutrons always equal in number?
Because they are both in the nucleus and if they weren't the element would be radioactive.
What occurs for two atoms to be isotopes of each other?
Two atoms are considered different isotopes of their element if they have different masses. This mass comes from the neutral-charged neutrons differing.
What is the the particles in the atom that account for most of the mass of the atom are protons and?
Neutrons is the answer. Both protons and neutrons have almost equal mass and concentrated in nucleus. Electrons have negligible mass as compared to mass of protons and neutrons and such minor figures are discarded in physics as much as mass isconcerned. Mass of electron is 1/1836 as compared to proton. But electric charge wise 'both' are equal and apposite.

What subatomic particle compose both protons and neutrons?
Protons and neutrons are part of the nucleus of an atom
How do electrons different from both protons and neutrons?
Electrons carry a negative charge, protons and neutrons do not.
What do protons and electrons have that neutrons do not?
Protons and electrons both have a positive or negative charge, but neutrons have no charge.
