The reactivity of an atom is due to its number and arrangement of __________ in the outer energy level (or orbit).
your question was confusing but I was able to interperet it.
the answer is Electrons
The orbital will be described with a number, followed by a letter, which may have a suffix. The number is the principal energy level. For example 2p, principal energy level 2; 5d principal energy level 5; 1s principal energy level 1.
The lowest energy level is NOT farthest from the nucleus. It is closest to the nucleus. The energy levels of an atom are expressed as negative numbers. In an energy level diagram the level nearest the nucleus will be the largest negative number. But again this means it is the lowest energy. For example, -8 is larger then -13.
A gold atom has 6 energy levels. Level 1: 2 electrons Level 2: 8 electrons Level 3: 18 electrons Level 4: 32 electrons Level 5: 18 electrons Level 6: 1 electron
Energy level is Energy level.
Mercury has 80 electrons distributed in 6 energy levels,; namely:First Energy Level: 2Second Energy Level: 8Third Energy Level: 18Fourth Energy Level: 32Fifth Energy Level: 18Sixth Energy Level: 2Accordingly, Mercury has on the outer shell 2 electrons to share with in any chemical reaction by an ionic bond.
By doing it this way, you can arrange them in a fashion in which you can predict their reactivity by the row that they're in. This is because they are lined up to account for a visualisation of how much of the energy level is filled with electrons
The electronic arrangement of chlorine is 2, 8, 7. This means that chlorine has 2 electrons in its first energy level, 8 electrons in its second energy level, and 7 electrons in its outermost energy level.
2nd energy level, the electron arrangement is 2,1 at ground state
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
The number and arrangement of electrons in atoms of an element determine the chemical properties of the element.
Potassium: - Electronic configuration: [Ar]4s1 - Electrons per shell: 2,8,8,1
The answer to this question is that the oxidation number for the 2nd energy level is +2. This is because the 2nd energy level is the second highest energy level in an atom, and thus has a higher oxidation number than the 1st energy level. The oxidation number for the 2nd energy level is determined by the number of electrons in the 2nd energy level.
The quantum number for that energy level.
the number of elements in the atom The group the element is in on the periodic table (how many valence electrons it has). Metals increase in reactivity from right to left on the periodic table and non metals increase in reactivity from left to right, with the exception of group group 18, which is not reactive, and Hydrogen, which is very reactive.
Krypton's reactivity level is low to none at all, since it's part of the inert gases family.
The emission spectrum is your visible light spectrum, so it tells you your wavelength and frequency. Knowing this information allows you to calculate your photon energy (Eph = hv, where v = frequency and h = plank's constant). Hence, you know how much energy the electrons have and how much energy it takes to excite them from one energy level to the next (Eph).
The orbital will be described with a number, followed by a letter, which may have a suffix. The number is the principal energy level. For example 2p, principal energy level 2; 5d principal energy level 5; 1s principal energy level 1.
