What did Rutherford say about the small number of particles that bounced straight back?
Rutherford fired alpha particles at a sheet of atoms in order to determine the atomic structure. The alpha particle is positively charged. Those particles that bounce straight back are the ones that hit the nucleus of the atom and were repelled by the nucleus's positive charge.
Greek name for platinum?
platina pi, lambda, alpha, tau, iota, nu, alpha
What are the 4 types of adrenergic receptors?
alpha 1, alpha 2, beta 1, beta 2
Is the particle with a plus 2 charge a an alpha particle b a gamma ray or c a beta ray?
a. an alpha particle
An alpha particle is equivalent to a hydrogen nucleus. True False?
False. An alpha particle is equivalent to a helium-4 nucleus.
What is the electrical charge of an alpha particle?
The electric charge of an alpha particle is positive. An alpha particle is a helium nucleus (which being a nucleus has a positive charge)
Alpha particle charge?
positive charge
Alpha beta gamma which is uncharged?
gama radiation is uncharged. Alpha is positive and beta is negative.
Are alpha particle negative or positive?
An alpha particle is a helium nucleus; it has a charge of +2.
Is alpha radiation usually positive or negative?
postive
Does alpha rays contains only a positive charge of atom?
Alpha rays are helium ions, He2+.
Why is alpha is a positive charged particle?
An alpha particle is a helium-4 nucleus - in other words, two protons + 2 neutrons. The protons have a positive charge, the neutrons are neutral.
What type of radiation produces positive and negative radiation?
a Alpha and Beta
What is the type of radioactive decay in which positive particles are given off?
It's called alpha-decay. The two protons and two neutrons are removed in the form of alpha particles, or helium nuclei.
What does prep's alpha chapter stand for?
PREPS Alpha Chapter is a Community Srevice Organization and it stands for Positive Responsible Elite Proud Students
Which type of radioactive emission has a positive charge and weak penetrating power?
alpha
Why fructose gives positive tollen reagent test?
Only aldehydes give a positive Tollens test. However, under the strongly basic conditions of the test, alpha-hydroxy ketones can isomerize to aldehydes, so they will also give a positive Tollens test. Fructose is an alpha-hydroxy ketone.
