Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all.

The atom is the smallest unit of an element that maintains the properties of that element. All atoms are composed of subatomic particles called neutrons (particles with no charge, neutral), electrons (negatively charged particles) and protons (positively charged particles).

The proton is located in the nucleus, an atom's central region. The number of protons in the nucleus is the atomic number, which determines the identity of an element. The neutron is located in the nucleus of an atom. Together, the total number of protons and neutrons in the nucleus determine the mass number of the atom.

The electron is likely to be found in the electron cloud, a region around the nucleus of an atom. The electrons located in the electron cloud interact with other atoms or ions when joining together to create a compound. A compound a substance made up of atoms or ions of two or more different elements joined by chemical bonds.

Hope that helps.

When Mrs. Green describes the physical properties of matter she said that physical properties often concern changes in state. On
dedylja [7]

Properties of matter can be broadly classified into two categories:

-Physical properties, these usually involve a change in the state of matter

-Chemical properties. these involve a change in the chemical composition of matter.

Now, physical properties can be further classified as:

Extensive: these depend on the amount of the substance, eg: mass, volume  

Intensive: these do not depend on the amount of the substance eg: density, color, melting point, boiling point

A physical property that does not describe a change in state is color. For example: copper sulfate is a compound which is a blue in color. Thus, color provides information which describes the appearance of matter. In contrast, properties like melting or boiling point suggests a change in the state of the substance.

Which statement describes the masses of the particles that make up an atom?
Novay_Z [31]
The mass of the atom is equal to the sum of the number of protons and the number of neutrons. In a neutral atom, the number of protons is equal to the number of electrons.  The atomic number meanwhile of an atom is equal to the number of protons of the atom.

What does the atmoic weight 1 in hydrogen tell scientists
Paul [167]

Explanation:

The atomic number is equal to the number of protons in an atom's nucleus. Hydrogen's atomic number is 1 because all hydrogen atoms contain exactly one proton.

If ice is warmed and becomes a liquid, which type of process is it?
ser-zykov [4K]
If ice is warmed and becomes a liquid, the process is endothermic.

The process requires heat in order to proceed. If ice stays in a very cold place, it will not melt unless it's heated. If ice is placed outside where it melts on its own, it gets the heat from the surroundings.
