What are 3 atoms that have the highest electronegativities?
C.Atoms with a small atomic radiusD.Atoms to the right on the periodic table
Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
Who described atoms as small spheres that could not be divided into anything smaller?
John Dalton (he mentioned about this in his atomic theory).
What form of energy associated with the motion of small particles of matter?
Please be more specific. Small respect to what? Are you talking about the motion of atoms or the motion of sub atomic particles?
What do scientists use since atoms are too small to examine under normal conditions?
models
Electronegativity increases when atoms .?
B. are located on the right on the Periodic TableC. have a small atomic radius

What atomic process combines nuclei of small atoms to form massive nuclei?
FUSION
Which subatomic particle has such a small mass that is not used to calculate the atoms atomic mass?
electron
What did Rutherford infer as a result of his observations?
Rutherford Discovered Many key factors of the atom. Especially about Protons and Electrons. He Did Not Know about neutrons. He Concluded That The atoms electron cloud was positive and electron floated around it like chocolate chips in a cookie.
Does platinum have small atoms?
Platinum contains 117 neutrons and the atomic number for platinum is 17.
What are the very small particles of which matter is composed?
Atoms, which are in turn composed of sub-atomic particles.
What states that matter is composed of atoms?
The ATOMIC THEORY states that all matter is composed of very small particles called atoms, and that those atoms cannot be broken apart.
How to draw the atomic structure of a compound?
Atomic structure is drawn by considering atoms as small spheres & bonds are represented by line joining the centre of two spheres.
What is the empirical formula of a compound that contains 57 percent sulfur and 43 percent oxygen by mass?
Since the atomic mass of sulfur is very close to twice the atomic mass of oxygen, the ratio of numbers of oxygen atoms to numbers of oxygen atoms is close to 43:28.5. The closest ratio of small integers is 3:2; therefore the empirical formula is S2O3.
What is the definition of the word atomic?
1.Of or relating to an atom or atoms.2. Of or employing nuclear energy3. Very small; infinitesimal.
Are electrons small bits of matter?
Yes. They are sub-atomic particles. In other words they make up parts of atoms.
