It is impossible to divide an atom into smaller parts.
There are electrically neutral particles inside atoms.
Atoms contain small, negatively charged particles.
Answer: The correct statement is atoms contain small, negatively charged particles.
Explanation:
J.J.Thomson was a scientist which discovered electrons that are present in an atom.
He did an experiment and gave a model for this. The experiment conducted by him was Cathode Ray experiment and the model given by him was Plum pudding model.
From cathode ray, he showed that the cathode ray was composed of a negatively charged particles and named it as electrons. From plum pudding experiment, he said that the electrons are embedded in the atom. These particles carry negative charge and are very small as compared to the atom.
Hence, the correct statement is atoms contain small, negatively charged particles.
Answer:
1 mol of sucarose has 7.22 x10²⁴ atoms of C, 1.32 x10²⁵ atoms of H and 6.62 x10²⁴ atoms of O
Explanation:
C12H22O11 is the molecular formular for sucarose
So in 1 mol of sacarose, we have 12 mols of carbon, 22 moles of hydrogen, and 11 mols of oxygen.
As you know, 1 mol has 6.02x10²³ atoms so these are the rule of three to calculate the number of atoms of each type.
1 mol ______ 6.02x10²³
12 moles ______ 12 . 6.02x10²³ = 7.22 x10²⁴
22 moles ______ 22 . 6.02x10²³ = 1.32 x10²⁵
11 moles _______ 11 . 6.02x10²³ = 6.62 x10²⁴
Answer:
The correct answer is non-metals.
Explanation:
In the covalent bond, the two non-metallic atoms share one or more electrons, i.e., they bind through their electrons in the last orbital. Covalent bonds normally occur between atoms with similar and elevated electronegativity, from which removing the electron completely requires a lot of energy.

b.a nitrogen-nitrogen single bond
c.each nitrogen has one nonbinding electron pair
d.each nitrogen has two nonbinding electron pairs
e.each hydrogen has one nonbonding electron pair
The lewis structure of n2h2 shows
c. each nitrogen has one nonbinding electron pair
Lewis structures are diagrams that show the bonds between the atoms of a molecule and the lone pair of electrons that might exist in a molecule.
Lewis structures can be drawn for each covalently bonded molecule, as well as coordination compounds. The Lewis structure is named after Gilbert N. Lewis, who introduced in his 1916 article The Atom and the Molecule. The Lewis structure extends the concept of the electron point diagram by adding lines between atoms to represent pairs together in chemical bonds.
The Lewis structure shows each atom and its position in the molecular structure using its chemical symbol. Lines are drawn between atoms that are bound to one another (pairs of dots can be used instead of lines). The excess electrons that make up lonely pairs are represented as pairs of points and are placed next to the atom.
The number of electrons represented in the Lewis structure is equal to the number of valence electrons in each atom. Non-valence electrons are not represented in the Lewis structure.
In the case of Lewis structures, formal charges are used in the description, comparison, and assessment of the topological and resonant structures that might occur by determining the apparent electron charge of each atom, based on the structure of the electron points, assuming exclusive covalence or non-polar bonds. Formal charges have been used in determining possible electron reconfigurations when referring to reaction mechanisms, and often produce the same sign as the partial charge of atoms, with the exception.

A transversewave is a wave is a wave in which the particles in the medium oscillate in a direction that is perpendicular or at 90 degrees to the direction in which the wave propagates. Light waves or electromagnetic waves are a good example of transverse waves. When an electromagnetic wave propagates, the medium in which it propagates vibrates in a direction perpendicular to the direction of travel.
A longitudinal wave is a wave in which the particles of the medium oscillate in a direction parallel to the direction in which the wave is travelling. Sound waves are good examples of longitudinal waves. When sound propagates, the particles of the medium which it travels through will vibrate in the direction in which the wave is travelling.
Similarities
Differences
The main difference is that for longitudinal waves, the particles in the medium will vibrate in the direction of the wave and that for transverse waves, the motion of the particles in the medium is in a direction perpendicular to the direction of propagation of the wave.
