What is the first quantum number of a 2s2 electron in phosphorus 1s22p63s23p3?
The first quantum number is the principal quantum number (n), which indicates the main energy level of an electron. For a 2s electron in phosphorus (atomic number 15), the first quantum number is 2.
The atomic number of an element indicates the number of .. in an atom?
The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
What is the correct electron configuration for the element Zn?
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
In what period is the element located on the periodic table?
The element's location on the periodic table indicates its period, which corresponds to the number of electron shells in its atomic structure.
What can be said about the electron configurations of all the elements in a group?
Elements in a group have the same number of valence electrons, giving them similar electron configurations. The electron configurations differ by the number of filled inner shells, leading to a trend in chemical reactivity within the group. The periodic table is organized based on these similarities in electron configurations within groups.
What electron configurations indicates an atom with atomic number of 24?
Chromium (24Cr) electron configuration: [Ar] 3d5 4s1 Complete [1s2, 2s2 2p6, 3s2 3p6] 3d5, 4s1
What is the abbreviated electron configurations for Titanium?
The abbreviated electron configuration for Titanium (Ti), which has an atomic number of 22, is [Ar] 3d² 4s². This notation indicates that Titanium has the same electron configuration as Argon ([Ar]), followed by two electrons in the 3d subshell and two electrons in the 4s subshell.
The atomic number of a compound indicates the?
The atomic number refers to the number of proton in a particular atom. As a matter of fact, number of proton = number of electrons in an atom. The number of electron changes as the atom forms ion.
What of the following is the correct electron configuration for Al (atomic number 13)?
The correct electron configuration for aluminum (Al), which has an atomic number of 13, is 1s² 2s² 2p⁶ 3s² 3p¹. This configuration indicates that aluminum has two electrons in the 3s subshell and one electron in the 3p subshell, following the filling order of the atomic orbitals.
What is the first quantum number of a 2s2 electron in phosphorus 1s22p63s23p3?
The first quantum number is the principal quantum number (n), which indicates the main energy level of an electron. For a 2s electron in phosphorus (atomic number 15), the first quantum number is 2.
The atomic number of an element indicates the number of .. in an atom?
The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
What does the number beneath carbon indicates?
The number beneath carbon in the periodic table indicates its atomic number. Atomic number is the number of protons in the nucleus of an atom of that element.
What is the electron configurations of selenium?
Atoms of the element selenium (atomic number 34) have the electron configuration 1s2, 2s2, 2p6, 3s2, 3p6, 4s2,3d10, 4p4
The number of protons in the nucleus indicates the atoms?
It indicates the atomic number
What do elements in same atomic period have?
Elements in the same atomic period have the same number of electron shells. This means that they have similar properties related to the number of energy levels in their electron configurations. However, their chemical properties can vary due to differences in the number of electrons in their outermost shell.
Why does proton and electron are equal atomic number?
They have not atomic numbers. Atomic number is made by number of protons an atom has.
