How can matter made of the same properties look so different?

Matter looks different and behaves differently when it changes from one state to another. All particles of matter are in constant random motion. Particles of liquid water have less energy and move slower than particles of water vapor.

What determines if elements are the same?

The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as “isotopes”.

Are made up of atom or atoms of the same kind?

Element : A pure substance composed of the same type of atom throughout. Compound : A substance made of two or more elements that are chemically combined in fixed amounts.

How is matter combined?

Different states of matter can be mixed without making a chemical change. You can mix solids with solids, solids with liquids, and liquids with liquids. You can mix gases with gases, and liquid with gases. These combinations of materials are called mixtures.

How do properties of matter make them useful for different purposes?

Properties like shape and mass may be different for different objects, even when they are made of the same material. Density is a useful property for making comparisons between different materials.

What are two things that are elements in the same group make them similar?

All the elements in one group have the same number of valence electrons. The valence electrons are those on the energy level the most distant from the nucleus. These valence electrons are those involved in bonding with other atoms to form compounds.

What are two things that elements in the same group have that make them similar?

The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.

What is made up of same kind of atoms?

Elements are made up of same kind of atoms.

What is having same kind of atoms?

The answer is element.

How are the elements in the same column similar?

The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.

What is similar about elements in the same group?

What is the difference between a pure element and an element?

Chemists and nuclear scientists have different definitions of a pure element. In chemistry, a pure element means a substance whose atoms all (or in practice almost all) have the same atomic number, or number of protons. Nuclear scientists, however, define a pure element as one that consists of only one stable isotope.

Why is the proximate matter of two things different?

Each level of matter is a compound of the matter at the level immediately below it and a form. If the proximate matter of two things is to be different, despite their lower-level matter being the same, the reason must be that the forms of the proximate matters are different.

What is the difference between form and matter?

Form is matter-involving, but that is not to say that it has its own form or essence and its own matter. Form and matter are introduced to explain certain facts about ordinary objects of perception, such as this man or this horse.

Are atoms of the same element in different electronic states identical?

No, they are still not identical. Two atoms of the same element and in the same electronic state could be traveling or rotating at different speeds, which affects their ability to chemically bond.
