The plum pudding model best represents J.J. Thomson's mental image of an atom. In this model, electrons are embedded within a positively charged "pudding," similar to how seeds are embedded in a watermelon.
The symbol Na typically represents a neutral sodium atom with 11 protons and 11 electrons. If a sodium atom loses an electron, it becomes a positively charged sodium ion (Na+).
The size of a cesium atom is around 260 picometers (pm), which is equivalent to 0.26 nanometers or 2.6 angstroms. This measurement represents the typical radius of a cesium atom.
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which represents the number of protons and electrons in a neutral atom.
There are 9 protons in this fluorine atom because the atomic number (9) represents the number of protons in an atom.
The plum pudding model best represents J.J. Thomson's mental image of an atom. In this model, electrons are embedded within a positively charged "pudding," similar to how seeds are embedded in a watermelon.
Dalton's mental image of an atom can be best represented by a solid, indivisible sphere with no internal structure, similar to a billiard ball. This model suggested that atoms were the smallest, fundamental particles of matter.
im awesome!
Thompson described his model as plum pudding. Since not many people even know what plum pudding is, i like to describe his model as a scoop of chocolate chip ice cream. Imagine the vanilla ice cream as the positive material and the chips as the negative material.
The Rutherford model involve a positive nucleus separated from electrons.
The nucleus of an atom represents most of an atom's mass.
The charge of the negative charge of electrons surrounding the nucleus of the atom.
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
Na^+ represents a sodium atom that has lost ONE ELECTRON.
J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
Democritus
The formula for water is H2O, where "H" represents one atom of hydrogen and "O" represents one atom of oxygen.
