All given elements belong to second period of periodic table. And we know that going from left to right along the period the number of shells (Principle Quantum Number) remains constant and the number of protons (atomic number) increases, due to this increase in nuclear charge the valence electrons are more attracted towards the nucleus resulting in decreasing the atomic radii, Hence, the atomic radii from larger to smaller radii are as ,
Li Be B C N Ne
Largest --------------------------------> Smallest
Oxidation: Mg (s) —> Mg2+ (aq) + 2e
reduction: Cu2+ (aq) +2e —> Cu(s)
redox reaction: Mg(s) + Cu2+(aq)—> Mg2+(aq) + Cu(s)
Answer: the distribution of electrons in the orbitals of its atoms
Explanation:
The electron configuration of an element describes _____. Multiple choice question.
the relationship between the nucleus of an atom and its electrons
the types of electronic energy levels that exist within an atom
the subatomic particles contained within an atom of the element
the distribution of electrons in the orbitals of its atomstal
Element 16 i sulfur
As element 16, it has 16 protons
The neutral atom then also has 16 electrons.
the electrons are b the 1s orbital 2e
2s orbital 2e
2p orbitals 6e
3s orbital 2e
3p orbitals 4e
(note 4 electrons in the 3p orbitals means 4 electrons in the "p" shaped orbitals at the 3rd energy level from the nucleus.
The electronic configuration for sulfur is written as
1s2 2s2 2p6 3s2 3p4
and can be obtained from a proper reading of the periodic table
Answer:
Potential energy.
Explanation:
Potential energy is the energy in a body due to its position.
Answer:
the answer is A because when something is going straight it wont change unless its acted upon by a force
