Why is the 2nd ionisation energy of Cr higher and not lower than of Mn?
The electron configuration of a neutral chromium atom is [Ar]3d54s1. The electron configuration for manganese is [Ar]3d54s2. The first electron removed from a chromium atom is the single 4s electron, leaving the electron configuration [Ar]3d5. The first electron removed from a magnesium atom is one of the 4s2 electrons, leaving the electron configuration [Ar]3d54s1. Removal of a second electron from a chromium atom involves the removal of one of the 3d electrons, leaving a configuration of [Ar]3d4, which is not a very stable configuration, and requires more energy to achieve. Removal of a second electron from a magnesium atom involves the removal of the second 4s electron, leaving a configuration of [Ar]3d5, which is more stable and requires less energy to achieve.
Where could an electron be found in a atom?
In an electron cloud, which a probability range circling around the atom. Due to the Heisenberg Uncertainty Principle, both an electron's location and speed can not be known at the same time. Therefore, a range is created.
Which noble gas has an electron structure like the ions in magnesium oxide?
Neon: In forming magnesium oxide from the elements, two electrons leave each magnesium atom and transfer to an oxygen atom. Therefore, both the magnesium cation and the oxygen anion have the electron configuration of neon, which has an atomic number 2 greater than oxygen and 2 less than magnesium.
What noble gas has the same electronic configuration as fluorine?
K+ and argon have the same electron configuration
Electron Configuration of Chlorine-35 the same or different as Chlorine-37?
They're the same, they both have 17 protons and 17 electrons. The only difference is that Cl-35 has 18 neutrons, whereas Cl-37 has 20. Both have the electron configuration of [Ne] 2s2 3p5
Which ion has the same electron configuration as an atom of He?
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
How is the electron configuration for both a cation and a anion differ from its neutral atom?
Let us assume that we have Sodium (Na), it has the ground state electron configuration of: [Ne]3S1. The ANION is negative, and thereby has more electrons, the Na anion(Na.) would have the following electron configuration: [Ne]3S2. The CATION(which is a positive ion) of Na(Na+) would have [Ne] as it electron configuration(as it loses an electron and becomes "equal" to Neon)

Why group 17 elements are strong non metals while group 1 elements are strong metals?
All elements tend to react with other elements so as to attain a noble gas electronic configuration in their ions, because such a configuration usually has the lowest energy for a particular atom or ion, other factors being equal. The drive to form such an ion is strongest when the electron configuration of an elemental atom differs from the closest noble gas configuration by only one electron, and this criterion is true for both group and group 17 elements: Group 1 elements can attain a noble gas electron configuration by donating one electron to another atom, and Group 17 elements can attain a noble gas configuration by accepting one electron, thereby filling their valence shell.
If a bromine atom attracts electron from potassium atom what happens to both?
positively
What electron and neutron have in common?
They are both particles in an atom
Does a metallic atom and a nonmetallic atom both gain electron?
No. A metallic atom will typically lose electrons.
Where could an electron be found in a atom?
In an electron cloud, which a probability range circling around the atom. Due to the Heisenberg Uncertainty Principle, both an electron's location and speed can not be known at the same time. Therefore, a range is created.
What does both an atom and a nucleus contain?
An Atom's nucleus contains protons and neutrons. Surrounding them is the electron cloud.

What noble gas has the same electronic configuration as fluorine?
K+ and argon have the same electron configuration
Which is smallest in size - atom or electron?
An Atom contains both Protons & Electrons, and sometimes even Neutrons. An Electron is about 1/1840th the mass of a Proton or a Neutron, so Atoms are definitely much heavier.
