Answer: A solid has a defined shape and volume. A common example is ice.
A liquid has a defined volume, but can change state. An example is liquid water.
A gas has neither a defined shape nor volume. Water vapor is an example of a gas
Answer:
electrons
Explanation:
When elements combine to form compounds, chemical bonds form between the atoms. Bonds form when atoms share or exchange electrons in a way that gives each atom a complete outer shell.
For example:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations and have complete octet.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive. Both have complete octet.
C or a i really cant be sure i need brainlest plz
most likely a
