Q. What are the atomic number and the atomic mass of the element formed when polonium 218 emits a beta particle what are they if the polonium atom emits an alpha particle?
What are the atomic number and atomic mass of teh element formed when Po-218 emits a beta particle? What are they if the polonium emits an alpha particle? After beta emission from polonium, the atomic number increases by 1 and becomes 85, and the atomic mass is uncharged at 218.
Q. What element has an atomic mass of 218?
Polonium-218

Q. When Po 218 emits a beta particle it transforms into a new element What are the atomic number and atomic mass of this new element?
When emits a beta particle, its atomic number increases by one and its atomic mass remains unchanged. The resulting atom will be atomic number 85 and its atomic mass is 218. The reaction can be written as follows: 84218Po84218Po+ 85218At10βwhere 10βrepresents the emitted electron. B)
Q. What particle is produced when a PO 218 atom undergoes alpha decay?
lead
Q. What is balanced equation when 218 84 Po emits an alpha particle?
Answer and Explanation: The nuclear reaction is: 21884Po→21482Pb+42α 84 218 P o → 82 214 P b + 2 4 α .
Q. Which type of radiation is least penetrating?
There are three types of nuclear radiation: alpha, beta and gamma. Alpha is the least penetrating, while gamma is the most penetrating.
Q. Which type of radiation is the last penetrating?
The last kind of radiation is electromagnetic radiation, like X-rays and gamma rays. They are probably the most familiar type of radiation because they are used widely in medical treatments. These rays are like sunlight, except they have more energy. Unlike the other kinds of radiation, there is no mass or charge.
Q. What are 4 types of radiation from the sun?
Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Q. What type of radiation can be stopped by aluminum?
gamma rays
Q. Which two types of radiation have no charge?
Gamma rays are caused by changes within the nucleus. They are part of the electromagnetic spectrum and so travel at the speed of light. They have no mass and no charge.
Q. How do you know what type of radiation is emitted?
To determine the type of radiation (alpha, beta or gamma), first determine the background count rate, then the source count rate with no absorber. Next, place a sheet of paper between the source and the monitor. If the counts are significantly reduced, the source emits alpha particles.
Q. Which is a biological effect of low exposure to radiation?
Low doses may damage or alter a cell’s genetic code, or DNA. High doses can kill so many cells that tissues and organs are damaged immediately. This in turn may cause a rapid body response often called Acute Radiation Syndrome.
Q. Which type of radiation is blocked by the skin?
Alpha Particles In other words, these particles of ionizing radiation can be blocked by a sheet of paper, skin, or even a few inches of air.
Q. What organ in the body protects us from radiation?
Radiological Damage Our skin also contains melanocytes that produce a pigment called melanin. This protects the body from radiological damage via the sun’s UV radiation (or that from tanning beds).
Q. What is the most vulnerable organ in the body?
Your lungs are your most vulnerable organ.
