Answer:

$\huge\rm\underline\purple{Answer:-}$ Hund's rule : Every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied and all electrons in singly occupied orbitals have the same spin. The image attached is the example of hund's rule. $</head><body><div class="container"><div id="cube"><div class="front">Hope It</div><div class="back">Hope It</div><div class="right">Hope It</div><div class="left">Helps</div><div class="top">Helps</div><div class="bottom">Helps</div></div></div><style>body {padding-left: 30%;padding-top: 5%;}.container {width: 200px;height: 200px;position: relative;-webkit-perspective: 1000px;-moz-perspective: 1000px;}#cube {width: 100%;height: 100%;position: absolute;-webkit-transform-style: preserve-3d;-webkit-animation: rotatecube 10s infinite;-moz-transform-style: preserve-3d;-moz-animation: rotatecube 10s infinite;}#cube div {width: 200px;height: 200px;display: block;position: absolute;border: none;line-height: 200px;text-align: center;font-size: 50px;font-weight: bold;}@-webkit-keyframes rotatecube {0% { -webkit-transform: rotateX(0deg) rotateY(360deg) rotateZ(90deg); }25% { -webkit-transform: rotateX(90deg) rotateY(270deg) rotateZ(180deg); }50% { -webkit-transform: rotateX(180deg) rotateY(180deg) rotateZ(0deg); }75% { -webkit-transform: rotateX(270deg) rotateY(90deg) rotateZ(360deg); }100% { -webkit-transform: rotateX(360deg) rotateY(0deg) rotateZ(270deg); }}@-moz-keyframes rotatecube {0% { -moz-transform: rotateX(0deg) rotateY(360deg) rotateZ(90deg); }25% { -moz-transform: rotateX(90deg) rotateY(270deg) rotateZ(180deg); }50% { -moz-transform: rotateX(180deg) rotateY(180deg) rotateZ(0deg); }75% { -moz-transform: rotateX(270deg) rotateY(90deg) rotateZ(360deg); }100% { -moz-transform: rotateX(360deg) rotateY(0deg) rotateZ(270deg); }}.front {background: rgba(255,0,0,.5);}.back {background: rgba(0,255,0,.5);}.right {background: rgba(0,0,255,.5);}.left {background: rgba(0,255,255,.5);}.top {background: rgba(255,0,255,.5);}.bottom {background: rgba(255,255,0,.5);}#cube .front {-webkit-transform: rotateY(0deg ) translateZ( 100px );-moz-transform: rotateY( 0deg ) translateZ( 100px );}#cube .back {-webkit-transform: rotateX( 180deg ) translateZ( 100px );-moz-transform: rotateX( 180deg ) translateZ( 100px );}#cube .right {-webkit-transform: rotateY( 90deg ) translateZ( 100px );-moz-transform: rotateY( 90deg ) translateZ( 100px );}#cube .left {-webkit-transform: rotateY( -90deg ) translateZ( 100px );-moz-transform: rotateY( -90deg ) translateZ( 100px );}#cube .top {-webkit-transform: rotateX( 90deg ) translateZ( 100px );-moz-transform: rotateX( 90deg ) translateZ( 100px );}#cube .bottom {-webkit-transform: rotateX( -90deg ) translateZ( 100px );-moz-transform: rotateX( -90deg ) translateZ( 100px );}</style></body></html>$

Answer:

Hund's rule states that: Every orbital in a sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbitals have the same spin (to maximize total spin).
