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.
Daltons atomic therory?
In the 1800s John Dalton did some experiments and these are some of his magnificent work: * all elements are composed of atoms. atoms can not be divided or destroyed * atoms of the same element are alike * .atoms of different elements are not alike * the atoms of two or more elements can join together to form compounds
In what state of matter do atoms of all elements exist?
Atoms of all elements exist in the state of matter known as the gas phase.
What is the basic structure of all matter?
All matter is composed of atoms, which are made up of a nucleus containing protons and neutrons, surrounded by electrons in a cloud-like arrangement. Atoms can combine to form molecules, which are the basic building blocks of all substances.
What is the smallest amount of matter in an object?
The smallest amount of matter in an object is an atom. Atoms are made up of protons, neutrons, and electrons, which are the basic building blocks of all matter.
If all atoms in a sample of matter are alike that kind of matter is a?
an element
If all atoms in a sample of matter are alike that kind of matter is?
an element
What are substances in which all atoms are alike?
A substance in which all atoms are alike is an element.
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?
All neutrons are alike. As the name suggests , they are neutrally charged particles in the nucleus of an atom. They carry the same mass as a proton. They are found in the nucleus of an atoms together with the protons. However, atoms of a given element are isotopes of one another, if they have a different number of neutrons. e.g. Hydrogen , exhibits three isotopes. #1 protium ; 1 proton, 0 neutrons, 1 electron.( commonest isotope) #2 deuterium ; 1 proton, 1 neutron, 1 electron. ( heavy hydrogen) #3 tritium ; 1 proton, 2 neutrons, 1 electron. ( super heavy hydrogen and radio -active). Note in this table the number of neutrons in each isotope. The next element in the Periodic Table is Helium #1 helium ; 2 proton, 2 neutrons, 2 electron. Note the same number of neutrons as tritium , but now has two protons. A Neutron, in nuclear physics, can disintegrate to form a proton and an electron.
Who proposed the atom theory that all matter is composed of atoms and that all atoms of an element are alike?
John Dalton proposed the atom theory in the early 19th century. He suggested that all matter is made up of tiny, indivisible particles called atoms, and that all atoms of a specific element are identical in size, mass, and properties.
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.
A substance in which all atoms are not alike but all the molecules are alike?
nucleus compound
Are atoms an example of matter?
Yes. Atoms are matter. All the matter you encounter on Earth is made of atoms.
Do All atoms of an element have to be exactly alike?
yes they do
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
What are the similarities of atoms and matter?
Matter - basically all the matter in our surroundings - is made up of atoms.
