when Rutherford did his experiment he got a observation that very few alpha particles (helium ions ) got deflected from their mean position . This indicates that there is very tiny positively charged particle or object is present . This led to the result that Nucleus is positively charged .

What were the limitations of J.J Thomson atomic model?
J.J. Thomson's atomic model, known as the "plum pudding model," proposed that atoms consist of a positively charged "soup" with negatively charged electrons embedded within. However, it was limited in several ways: it could not explain the results of the Rutherford gold foil experiment, which demonstrated that atoms have a dense, positively charged nucleus. Additionally, Thomson's model failed to account for the discrete energy levels of electrons, as later shown by Bohr's model, and did not adequately explain atomic stability or the behavior of atoms in chemical reactions.
What is K plus?
K is the chemical symbol used to represent potassium. It is usually shown as K+ to indicate that it is positively charged.
Why are the central atoms shown as positively charged?
central atoms that are positively charged, either contain more protons than neutrons, or are simply made up of protons, therefore are not complete atoms. any imbalance of protons to electrons will make it no longer an atom but an ion. this is the only way it could be seen as positively charged because atoms are neutral.
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
If a charged sphere is brought close to a rod as shown in the figure above the pairs of pith balls suspended at the ends of the rod will?
When a charged sphere is brought close to the rod, it will induce a separation of charges in the pith balls at the ends of the rod. If the sphere is positively charged, the pith ball closest to the sphere will become negatively charged, while the one farther away will become positively charged. This results in an attractive force between the sphere and the nearest pith ball, while the two pith balls may also repel each other due to their like charges. Consequently, the pith balls will move towards the charged sphere.
Which of the atom shown has an atomic number of 7?
The atom shown with an atomic number of 7 is the nitrogen atom.
What is atomic nos?
Atomic nos probably is short for atomic number, that's shown on the periodic table on top of the atomic symbol.
What has rubbing done to the charges on the objects shown in diagrams A and B?
Rubbing has transferred some charge between the objects in diagrams A and B. In diagram A, the initially neutral object loses electrons, becoming positively charged, while in diagram B, the initially neutral object gains electrons, becoming negatively charged.
How can you figure out the number of electron an element has?
Finding the total number of electrons is easy. Assuming the atom is electrically neutal, the atomic number (always the number of protons) is also the number of electrons. This is because the protons are positively charged and the electrons are negatively charged, and a neutral atom will have a net charge of zero. Keep in mind, not all elements exist as atoms of their elemental state. Many of them are more commonly found locked up in compounds because they're just too reactive to exist solo.
What is the number of protons and electrons in ferrous ion?
Ferrous ions are iron atoms minus two electrons. An iron atom has 26 each of protons and electrons, as shown by the fact that the atomic number of iron is 26. Therefore, a ferrous ion has 26 protons and 24 electrons.
What is the relationship of atomic radii for each pair of species shown below?
The relationship of atomic radii for each pair of species shown below is that the atomic radius increases as you move down a group on the periodic table and decreases as you move across a period from left to right.
Is the atomic number the largest the two numbers shown in the periodic table?
The atomic number is the smaller of the two numbers shown in the periodic table. It represents the number of protons in the nucleus of an atom and determines the element's identity. The larger number, the atomic mass, is the sum of protons and neutrons in the nucleus.
