What is it called if all atoms substance are alike?
If all atoms in a substance are alike, the substance is called an element. Elements are pure substances that cannot be broken down into simpler substances by chemical means and are defined by the number of protons in their atomic nuclei. Each element has unique properties and is represented on the periodic table.
Are neutrons in the atoms of different elements alike?
neutrons of all atoms are alike
What is the average kinetic energy if all the atoms and molecules that make up a substance referred to as?
The average kinetic energy of the atoms and molecules in a substance is directly proportional to its temperature. It is a measure of the average motion of particles within the substance. The higher the temperature, the higher the average kinetic energy.
What is this substance in which the number of atoms is not important as long as all of the atoms are of the same type?
A substance where the actual number of atoms is not significant, as long as they are all of the same element, is called a chemical compound. This is because the properties of compounds are determined by the arrangement and types of atoms within the molecules, rather than their quantity.
What is the smallest part of a substance that has all the porperties of the substance?
Molecules are the smallest part of a substance. Molecules have all the properties of a substance.
What are substances in which all atoms are alike?
A substance in which all atoms are alike is an element.
When all atoms in a substance are alike the substance is a?
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
What is it called if all atoms substance are alike?
If all atoms in a substance are alike, the substance is called an element. Elements are pure substances that cannot be broken down into simpler substances by chemical means and are defined by the number of protons in their atomic nuclei.

If heat is removed from a substance how will atoms behave?
Kinetic theory of matter: All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. ... They contract when they lose their heat.
Which of these statements is false all neutrons are alike all electrons are alike all protons are alike all atoms are alike?
True statements: All neutrons are alike, all electrons are alike, all protons are alike (All atoms of a given isotope is only alike). False statement: All atoms are alike All atoms are not alike as they may vary in the number of protons / electrons / neutrons.
Are neutrons in the atoms of different elements alike?
neutrons of all atoms are alike
What is a pure substance - all the atoms have the same atomic number or number of protons?
A pure substance in which all the atoms have the same atomic number or number of protons is an element.

What is the meaning of the element and compound?
An element is a substance that consists of atoms that are all of the same type, meaning that they all have the same number of protons in their nuclei. A compound is a substance consisting of molecules, each consisting of the same atoms connected in the same way.
