Atoms

Question 1

Atom

Answer 1

The smallest unit of an element

Question 2

Nucleus

Answer 2

The central part of an atom made of protons and neutrons, most of an atoms mass

Question 3

Newtron

Answer 3

uncharged particle

Question 4

proton

Answer 4

positively charged particle

Question 5

Electron

Answer 5

Negatively charged particle

Question 6

molecule

Answer 6

A molecule is the smallest particle in a chemical element or compound

Question 7

quarksyou

Answer 7

any of a number of subatomic particles carrying a fractional electric charge,

Question 8

Alkali metals

Answer 8

Alkali metals are in group 1 and are the most reactive to water

Question 9

Noble gases

Answer 9

Noble gases are the least reactive

Question 10

Cation

Answer 10

cations are elements with a positive charge when electrons are removed from an actual atom

Question 11

Anions

Answer 11

anions are elements with a neg

Question 12

valence shell

Answer 12

The valence shell is the outermost shell of an atom in its uncombined state, which contains the electrons most likely to account for the nature of any reactions involving the atom and of the bonding interactions it has with other atoms.

Question 13

valence electron

Answer 13

In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Question 14

octet

Answer 14

The octet rule is a chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas.

Question 15

Ion

Answer 15

an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
