By atomic models I assume you mean how we say an atom works and is arranged.
There have been three major atomic models in history:
The plum-pudding model said that negatively-charged particles (the precursor to electrons) were suspended in a positively-charged "soup" (the plum pudding).
Rutheford disproved this model with his experiments, which led to Niels Bohr inventing the Bohr model of the atom, which has electrons orbiting the nucleus in predefined orbits (called "orbitals"). Although we know that the Bohr model is incorrect, it is very close to the correct (quantum-mechanical) model, so that's what is taught in most elementary and high schools.
Nowadays, only the third model is considered correct: the quantum mechanical model. It is based on Max Planck's quantum theory and involves electrons flying around in three-dimensional clouds (also called "orbitals"). The QM model is pretty complex but it's rather simple compared to string theory and other physics concepts.
What else can I help you with?
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
What are atoms that have the same atomic number but different neutron numbers?
Atoms that have the same atomic number but different neutron numbers are known as isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in their atomic mass.
Why scandium and boron in different groups?
They have different atomic numbers.
Why can an atom have more then one mass number but only one atomic number?
First of all, an atom can not literally have either more than one mass number or more than one atomic number. Different atoms of the same element can have different mass numbers but the same atomic number because the atomic number is the defining characteristic of an element, but many elements have isotopes that have different numbers of neutrons in their nuclei and therefore different mass numbers: Mass numbers are the sum of the numbers of protons and neutrons in the nucleus.
What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
Form of an element having different atomic and number of neutrons?
Isotopes have different numbers of electrons, but not different atomic numbers (numbers of protons) or they'd be different elements.
Do isotopes of an element have the same atomic mass but different atomic number?
The different mass numbers are due to different numbers of neutrons.
Isotopes of hydrogen have different atomic what?
Atomic mass and different numbers of neutrons.
Why atomic number of different elements are different?
Because different elements have different numbers of protons, which determines the atomic number.
What are atoms that have the same atomic number but different neutron numbers?
Atoms that have the same atomic number but different neutron numbers are known as isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in their atomic mass.
Why scandium and boron in different groups?
They have different atomic numbers.
Isotpes of elements have different?
atomic numbers
Why can an atom have more then one mass number but only one atomic number?

Different atoms of the same element can have different mass numbers but the same atomic number because the atomic number is the defining characteristic of an element, but many elements have isotopes that have different numbers of neutrons in their nuclei and therefore different mass numbers: Mass numbers are the sum of the numbers of protons and neutrons in the nucleus.
How can different atoms of the same element have the same atomic number but can have different mass numbers?
They have different numbers of neutrons.
What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
Does an isotope of an element have a different atomic mass?
Yes, isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This is why the atomic mass on the periodic table is often listed as a range for an element.
Why does the atomic mass of some elements is shown as a decimal value?
Many atoms exist in the form of different isotopes. These have different numbers of neutrons and so their atomic masses are different. The atomic mass for the element is the average of these masses, weighted together according to their abundance.
