An atom consists of a centrally located nucleus and three types of subatomic particles known as electrons, protons, and neutrons. Answer and Explanation: The correct answer is (b) Protons and neutrons. The protons and neutrons are the ...
Proton is a subatomic particle that lives inside the nucleus of an atom. It is positively charged and has a charge equal and opposite to that of an electron. Proton, together with a neutron, is responsible for most of the mass of an atom. Answer ...
Atomic structure Grams are not used to measure mass of atoms because atoms are too small –Amu is used instead –Amu = atomic mass unit Amu – 1/12 th the mass of a carbon-12 atom, which contains 6 protons and 6 neutrons Isotopes Isotopes are atoms that have the same number of proton...
Lead is very dense which is why it is often used to block radiation. Its density is 11.34 g/cm3. This means that if you had a cube that was 1 cm x 1 cm x 1cm it would have a mass of 11.34 g. By comparison, the same sized cube of gold would weigh 19.30 g. So a cube of ...
How many protons does it have? The mass number of an atom depends primarily on the number of a. protons and neutrons. b. positrons. c. neutrons and electrons. d. protons and electrons. What is the term for the total number of protons and neutrons of the nucleus of an atom? An ...
Quick (but challenging) Quiz. 3. Isotopes of an element have… the same mass number. different atomic numbers. the same number of protons but different mass numbers. the same number of protons but different numbers of neutrons.
You have Ep1i, pp1i, and the velocities of the protons in the zero-momentum frame. Now you need to transform back to the lab frame. Look at what @PeroK wrote back in post 12. Nov 9, 2019 #39 Kharrid 27 0 vela said: You have Ep1i, pp1i, and the velocities of the pr...
Atomic mass: It is generally expressed in terms of atomic mass unit ( amu ) which denotes the average number of protons and the neutrons present in the element considering the abundance of the isotopes for the element. Isotopes: Isotopes of the element h...
