Write the isotope notation for an element with 5 protons and 6 neutrons.
Korolek [52]

The isotope notation : \large {{{11} \atop {5}} \right X}

<h3> Further explanation </h3>

Given

53 protons and 20 neutron

Required

The isotope notation

Solution

Isotopes are elements that have the same atomic number with a different mass number

The following element notation,

 \large {{{A} \atop {Z}} \right X}

X = symbol of element

A = mass number

   = number of protons + number of neutrons

Z = atomic number

   = number of protons = number of electrons, on neutral elements

So the mass number of element = 5 + 6 11

Atomic number = 5

The symbol :

\large {{{11} \atop {5}} \right X}

The force between two atoms is the result of _____________________ repulsion, nucleus-nucleus ________________, and nucleus-elec
Elanso [62]

Answer:

<h2>(1). electron electron repulsion</h2><h2>(2). repulsion </h2><h2>(3). attraction </h2><h2>(4). maximum attraction  </h2><h2>(5). attractive </h2><h2>(6). repulsive </h2><h2>(7). maximum attraction </h2><h2>(8). molecule </h2>

Explanation:

The same charges repel each other while opposite charges attract each other. During electron-electron interaction repulsion take palace because the electron has negative charges. Nucleus has positive charges so the interaction between two nucleus results in the form of repulsion. When interaction takes place between nucleus and electron then attraction takes place between nucleus and electrons due to opposite charges.

          The formation of a bond that takes place due to the sharing of the electrons is known as a covalent bond and thus the covalent molecule is formed.

What does covalent and ionic bond have to do with chemical bond?
krok68 [10]
Covalent and ionic bonds are two different types of chemical bonding.  Covalent bonds involve the sharing of electrons between 2 atoms while ionic bonds involve the complete transferring of electrons from one atom to another.  Covalent bonds usually form between two nonmetals while ionic bonds usually form between a metal and a nonmetal.   
I hope this helps.  Let me know if anything is unclear.
