Vocab Physical science

What are Electron

• toys

• atoms

• lights

• N/A

what are Electron cloud

• A group of electrons circulating around a nucleus or a molecule.

• Can it power something

• can it move something

• N/A

what are Neutron

• Is it good or bad

• does it have something to do with science

• 1. a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

• N/A

What does Nucleus

• I don't know

• is it good or bad

• the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.

• N/A

what are Proton

• does it help

• is it good or bad

• N/A

• a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign

what are Valence Electrons

• Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

• how do it help

• I don't know

• N/A

What are Atomic number

• 1. the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.

• does it mean 1234

• I don't know

• N/A

what does Atomic Mass Number

• An element's or isotope's atomic number tells how many protons are in its atoms. An element's or isotope's mass number tells how many protons and neutrons in its atoms

• N/A

• I don't know

• how does it help

what are Isotope

• do we use it

• Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

• N/A

What is Diatomic

• Consisting of two atoms

• Do it work

• Do we use it

• N/A
