the nucleus is made of protons and neutrons together. the protons have a positive charge and the neutrons have no charge [electrons circle the nucleus and have a negative charge]
False. An alpha particle is equivalent to a helium-4 nucleus.
The nucleus of an atom doesn't contain electrons, but it does contain protons and neutrons.
The first two statement are false. The other one is true. There are electrons outside the nucleus, but they are much lighter than the particles in the nucleus.
true but his experiment proved him wrong :)
True.
Assuming the context of this question is atomic physics, the answer is "false" for two reasons: 1) the atomic nucleus is positively charged. 2) the atomic nucleus a tightly bound composite of many particles.
False. An alpha particle is equivalent to a helium-4 nucleus.
The atomic nucleus is electrically positive.
The atomic nucleus contain protons and neutrons.
TRUE
Yes.
Yes. that is right.
It is true that a charged particle is called an ion. Ions that are positively charged are called cations and ions that are negatively charged are called anions.
When a beta particle is emitted from a nucleus via Beta- decay, the mass number stays the same, and the atomic number goes up one, because one neutron is changed into one proton by Beta- decay.In Beta+ decay, the opposite is true. A proton is converted into a neutron, again keeping the mass number the same, but in this case reducing the atomic number by one.The ending result is different, however. In Beta-, the beta particle is an electron, while in Beta+, the beta particle is a positron.
The nucleus of an atom doesn't contain electrons, but it does contain protons and neutrons.
False as a generalization but true for some isotopes. The atomic number is the number of protons in a nucleus, which may coincidentally be the same as the number of neutrons but is not required to be.
No. Physical action will not change what particle a certain particle is.
