Carbon. The 6 indicates the atomic number.
Nuclear notation represents an atom by indicating its chemical symbol, atomic number, and mass number, typically written as ({Z}^{A}\text{X}), where (A) is the mass number, (Z) is the atomic number, and (X) is the element's symbol. For example, carbon-12 is written as ({6}^{12}\text{C}). In contrast, hyphen notation specifies the element followed by the mass number, such as carbon-12. This method is simpler and often used in informal contexts.
The number of neutrons in an atom is determined by subtracting the atomic number (number of protons) from the atomic mass number (total number of protons and neutrons) of that element. For example, carbon has an atomic number of 6 and an atomic mass number of about 12, so it has approximately 6 neutrons (12 - 6 = 6). The exact number of neutrons can vary in isotopes of an element.
There is no simple answer since it depends on their relative sizes, orientation and configuration. Assuming the shapes do not overlap, the result will be a polygon with 6 to 12 sides.
1/6 of 12 = 2 2/6 of 12 = 4 3/6 of 12 = 6 4/6 of 12 = 8 5/6 of 12 = 10

The element with this electron configuration is carbon (C). This electron configuration corresponds to 6 electrons, which is the atomic number of carbon.
The element with the nuclear symbol C is carbon. Its atomic number is 6, meaning it has 6 protons in its nucleus. Carbon is a nonmetallic element that is essential for life and has multiple isotopes.
The element with the electron configuration 1s2 2s2 2p6 3s1 is sodium (Na).
An isotope of Carbon (C-13).This C-13 isotope has a natural abundance of 1.1%. That means that 1.1% of all the Carbon atoms have this configuration.The most abundantly found isotope (C-12) has 6 protons, 6 neutrons and 6 electrons. 98.9% of all the Carbon atoms have this configuration.
An element is defined by the number of protons in the nucleus; for example, carbon always has 6 protons. Elements can also have different numbers of neutrons in the atomic nucleus, and each number of neutrons gives you a different isotope. So, there is the isotope called carbon 12, with 6 neutrons (12 nuclear particles in total) and there is also the isotope called carbon 14, with 8 neutrons (14 nuclear particles in total). Every element has a number of isotopes.
Iron has the electron configuration [Ar]3d64s2.
Nickel has the atomic number 28 so it has the electron configuration 1s22s22p63s23p64s23d8 .
The chemical symbol for the element with an electron configuration that ends with np², where n is the principal quantum number, is lead (Pb) when n = 6. In this case, the electron configuration would end with 6p². Another element with the same configuration for n = 5 is tin (Sn), with an electron configuration ending in 5p².
