What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
What two things does the atomic mass represent?
Atomic mass is the sum of the number of protons and neutrons in the nucleus. The reason it is typically found in decimal form is because it is using the average number of neutrons, from all the different isotopes of that element.
What describes and atom?
A negatively charged electron cloud surrounding a positively charged nucleus. Reason: The nucleus contains positively charged protons and neutral neutrons. The positive nucleus is surrounded by a negatively charged electron cloud.
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
What charge are neutrons in the magnesium atom?
All neutrons have a negative charge. That is the reason they are called neutrons.
What is the primary reason an atoms nucleus is unstable?
Increasing the ratio neutrons/protons in the nucleus the atom become unstable.
Does an atom with more neutrons have a positive charge?
No. Neutrons have no charge. They are neutral ... the main reason they're called NEUtrons.The total charge on an atom is not affected by the number of neutrons in its nucleus.
What is the reason for alpha decay process?
Alpha decay occurs because certain nuclei are unstable due to having too many protons or neutrons, causing them to emit an alpha particle (helium nucleus) to increase stability by reducing the number of protons and neutrons. This process helps the nucleus achieve a more balanced ratio of protons and neutrons, resulting in a more stable configuration.
Why mass number denoted by A?
Mass number is the total number of protons and neutrons. because the nucleus consists of protons and neutrons only, the sum of protons and neutrons is the total number of ALL the nucleons. note the term "ALL" here.. this is the reason why mass number is denoted as "A".
Is it correct to say The principal reason for her visit was for her gastritis?
No. The principal reason for her visit was her gastritis.

Why is it important that protons and electrons attract to each other?
The main reason that electrons and protons are dominant in matter is that these are stable particles and do not decay spontaneously. The neutron, which is unstable outside of a nucleus, is stable within the nucleus of an atom. The reason that the protons and neutrons are bound together is the strong nuclear force. The coulombic attraction between protons and electrons then binds the electrons to the nucleus to form an atom.
What was the principal reason for the family to hide themselves?
the principal reason for the family to hide themselves was to escape from Nazis

What is the force needed to hold together a nucleus?
Nuclear force- it is a force that exists between two or more nucleons, it is responsible for the bonding of the neutrons and protons. The reason itself is much more complicated because it involves quarks which are smaller than protons or neutrons.
What charge are neutrons in the magnesium atom?
All neutrons have a negative charge. That is the reason they are called neutrons.
