What are the key differences between stable and unstable nuclei?
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.
What happens to an unstable nuclei?
They give out radiation to become more stable.
What would happened to a stable nucleus in which the number of neutrons suddenly decreased?
The nucleus would become unstable because you need a certain amount of neutrons, electrons, and protons for it to be stable.
What is the antonym of stable?
the antonym of stable is unstable
Is Peru a stable country or unstable?
is peru government stable or unstable
What is the role of Physical therapy in the management of stable and unstable angina?
Physical Therapy is very helpful as its not only to balance the BP as it rises, but also other symptoms visible, can come under control.
How Can You Tell If You're Experiencing Angina Or a Heart Attack?
Coronary artery disease (CAD) is a condition that develops when the arteries that supply blood to the heart are occluded by fatty plaques. The heart does not receive sufficient oxygen and nutrients to function properly. CAD's primary symptom is angina.CAD is the number one cause of death throughout the world. In the U.S. it's estimated that half of all men and one-third of all women past the age of 40 will develop CAD at some point in their lives.What Is Angina?Angina is chest pain that develops when the heart isn't receiving enough oxygen. There are two types of angina:Stable angina: Stable angina occurs with activity or stress when the heart is working harder than usual. Its symptoms generally abate when the activity that initiated the episode ends. Individuals who suffer from stable angina can generally predict which activities will bring it on, how long an episode will last, and how long it will take for medication to relieve symptoms.Unstable angina: As its name suggests, unstable angina follows no pattern. Unstable angina can occur with or without physical exertion, and often the pain associated with unstable angina is far more severe than the pain associated with stable angina. Unstable angina is a medical emergency: Individuals suffering from unstable angina need medical attention right away.How Can You Tell Angina From a Heart Attack?Angina is not the same thing as a myocardial infarction or heart attack although the two sets of symptoms resemble one another. A heart attack is a more serious manifestation of CAD that takes place when the heart is deprived of oxygen for so long, heart cells start to die. Episodes of angina, particularly unstable angina, increase the likelihood that a heart attack may occur.Like a heart attack, angina is experienced as pain or pressure in the chest. Sometimes the pain will be associated with other symptoms such as sweating and respiratory difficulties. An angina episode usually lasts between one and ten minutes and subsides with rest.The pain associated with a heart attack, on the other hand, lasts longer than 10 minutes and does not go away with rest.An individual with a history of angina should seek medical attention immediately if:Chest pain occurs without exertionChest pain is more severe than previous angina episodesChest pain is accompanied by weakness, syncope or nauseaChest pain lasts longer than 20 minutes and appears to be worseningThree nitroglycerine tablets do not relieve the pain
How does a unstable atom with one valence electron become stable?
Generally by losing the one electron
Is the process of unstable atoms trying to become stable by emitting energy that is at a level high enough to ionize.?
Yes, unstable atoms can become stable by emitting excess energy in the form of ionizing radiation such as gamma rays, alpha particles, or beta particles. This process helps the atom achieve a more stable configuration by releasing the excess energy stored in its nucleus.
Describe unstable angina due to ischemia?
Unstable angina, which increases the risk of a heart attack, occurs more frequently, lasts longer, is more severe, and may cause discomfort during rest or light exertion.
Describe stable angina due to ischemia?
Stable angina occurs during exertion, can be quickly relieved by resting or taking nitroglycerine, and lasts from 3 to 20 minutes.
Does too many neutrons determine if an isotope is unstable?
An isotope with too many neutrons can be unstable for example Hydrogen-3 is unstable while hydrogen-1 and 2 are stable. But so can one with too few neutrons, for example lead-204 is unstable while lead-206, 207, and 208 are stable.
