How many energy levels would electrons of hydrogen and helium fill?
1st energy levels only in which hydrogen will have only one electron whereas helium will have two electrons.
How many electrons would a neutral atom of cadmium have?
The neutral atom of cadmium has 48 electrons.
How many valence electrons does a neutral oxygen atom have?
A neutral atom of oxygen would have 6 valence electrons.
How might the spectrum of an atom appear if its electrons were not restricted to particular energy levels?
A broad spectrum of all colors would be observed.
What charge would nitrogen have if it gained 3 electrons?
Nitrogen would have a neutral charge and eight valence electrons.
How many energy levels would electrons of hydrogen and helium fill?
1st energy levels only in which hydrogen will have only one electron whereas helium will have two electrons.
Niels Bohr predicted that the electrons would be found orbiting the nucleus in energy levels that could be compared to what?
Niels Bohr predicted that the electrons would be found orbiting the nucleus in specific energy levels that could be compared to the rungs of a ladder. He proposed that electrons can only exist in these discrete energy levels and that they move between levels by absorbing or emitting specific amounts of energy. This led to the development of the Bohr model of the atom.
How many electrons would a neutral atom of cadmium have?
The neutral atom of cadmium has 48 electrons.
Which energy holds no more tham 8 electrons?
Assuming you mean energy levels, I would say that you suck at asking questions.
If the first and second energy levels of an atom are full.what would be the total number of electrons in the atom?
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
Which neutral atom would have four electrons?
Beryllium has 4 electrons
Why a stairway is a good model for the energy levels in a atom?
A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.
How many electrons does it neeed to gain to have a full outer shell?
1st energy level- 2 electrons 2nd energy level- 8 electrons 3rd energy level- 18 electrons To calculate the number of electrons other energy levels can hold, use the formula 2n^2. For example, to calculate the number of electrons the fourth level can hold, the equation would be 2(4)^2. This means that the fourth energy can hold 32 electrons. Same process for other levels.
How many many electrons are needed in the outer energy levels of most atoms for the atom to be chemically stable?
Generally speaking, it would be 8 electrons, but there are many exceptions.
How many valence electrons does a neutral oxygen atom have?
A neutral atom of oxygen would have 6 valence electrons.
What is the element that has the smallest atomic number of all the elements and that has electrons in three different energy levels?
If it has electrons in three different energy levels, then it must be in period 3 of the periodic table. To have the fewest electrons, it would be in group 1. So, the element in group 1, period 3 is sodium (Na).
How might the spectrum of an atom appear if its electrons were not restricted to particular energy levels?
A broad spectrum of all colors would be observed.
