The sum of the exterior angles of a polygon is equal to 360 degrees.
The sum of two positive integers can never equal zero.
No, it could be a partial sum.
The sum of a [single] square equals the square.
The sum of the superscript in an electron configuration is equal to the atomic number.
The total number of electrons in an electron configuration is given by the sum of the individual electron counts for each subshell (i.e. s, p, d, f). For example, in the electron configuration for oxygen (1s^2 2s^2 2p^4), the total number of electrons is 8, which is the sum of 2 (s subshell), 2 (s subshell), and 4 (p subshell) electrons.
Nothing in particular.
To use the example of helium, which has theelectronic structure 1s2. The 1 refers to the orbital number (1, 2, 3 etc, also known as the principal quantum number), the letter refers to the orbital type (s, p, d, f which corresponds to the azimuthal quantum number), and finally the superscript 2 refers to the number of electrons in that orbital.So for helium's 1s2 we have 2 electrons in the 1s orbital (filling it).Another example could be atomic iron which has the [Ar] 3d6 4s2 configuration. This is the argon electronic structure (1s2 2s2 2p6 3s2 3p6), and then 6 electrons in the 3d orbitals, and 2 electrons in the 4s orbital as well.
Noble gas notation allows us to represent the electron configuration of an atom using the previous noble gas's electron configuration as a starting point. This simplifies writing electron configurations by condensing the notation and reducing repetition of long electron configurations.
The superscript is the atomic mass number, which is the sum of protons and neutrons. The subscript is the atomic number, which is the number of protons. For a hafnium nuclide with 107 neutrons, the superscript would be 180 (107 neutrons + 73 protons) and the subscript would be 73.
The electron configuration for sodium in the excited state would be 1s2 2s2 2p6 3s1 3p1. In the excited state, one of the electrons from the 3s orbital would be promoted to the 3p orbital, leading to this configuration.
Yes, the sum of infinite ones equal the sum of infinite twos.
The electron configuration of carbon is 1s^2 2s^2 2p^2, representing the distribution of electrons in its energy levels. This means that carbon has 6 electrons, with 2 in the first energy level and 4 in the second energy level.
The magnitude of the vector sum will only equal the magnitude of algebraic sum, when the vectors are pointing in the same direction.

Hyphen notation for the element iron is Iron-56. This notation represents the sum of the number of protons and neutrons in the nucleus of an iron atom.
