C r 3 + has 3 electrons removed from the outermost shell. Cu = 29 = 1s² 2s² 2p⁶ 3s² 4p⁶ 4s¹ 3d¹⁰. Cr = 24 = 1s² 2s² 2p⁶ 3s² 4p⁶ 4s¹ 3d⁵ 2. background: #1c1819; } Electronic configuration of . font-family: Open Sans; body { background:#FFF; }.cnt article h1.entry-title a { color:#333; }.cnt article h2.entry-title a { color:#333; }.bSe h1, h1.entry-title, h1.entry-title a { color:#333; }.bSe h2 { color:#464545; }.bSe h3 { color:#333; }.bSe h4 { color:#333; }.bSe h5 { color:#333; }.bSe h6 { color:#333; }.bSe p, .mry .awr-e p { color:#666; }.cnt .bSe { color:#666; }.cnt h1 a, .tve-woocommerce .bSe .awr .entry-title, .tve-woocommerce .bSe .awr .page-title{font-family:Open Sans,sans-serif;}.bSe h1{font-family:Open Sans,sans-serif;}.bSe h2,.tve-woocommerce .bSe h2{font-family:Open Sans,sans-serif;}.bSe h3,.tve-woocommerce .bSe h3{font-family:Open Sans,sans-serif;}.bSe h4{font-family:Open Sans,sans-serif;}.bSe h5{font-family:Open Sans,sans-serif;}.bSe h6{font-family:Open Sans,sans-serif;}#text_logo{font-family:Open Sans,sans-serif;}.cnt h1 a { font-weight:500; }.bSe h1 { font-weight:500; }.bSe h2 { font-weight:500; }.bSe h3 { font-weight:500; }.bSe h4 { font-weight:500; }.bSe h5 { font-weight:500; }.bSe h6 { font-weight:500; }.cnt{font-family:Open Sans,sans-serif;font-weight:400;}article strong {font-weight: bold;}.cnt p, .tve-woocommerce .product p, .tve-woocommerce .products p, .brd ul li, header nav ul li a, header nav ul li > ul li a, .has-extended.has-heading .colch, footer, footer .fmm p, .aut-f{font-family:Open Sans,sans-serif;font-weight:400;}article strong {font-weight: bold;}.bSe h1, .bSe .entry-title { font-size:46px; }.cnt { font-size:18px; }.thrivecb { font-size:18px; }.out { font-size:18px; }.aut p { font-size:18px; }.cnt p { line-height:1.5em; }.thrivecb { line-height:1.5em; }.bSe a, .cnt a { color:#1e73be; }.bSe .faq h4{font-family:Open Sans,sans-serif;font-weight:400;}article strong {font-weight: bold;}header nav > ul.menu > li > a { color:#000000; }header nav > ul.menu > li > a:hover { color:#dd3333; }header nav > ul > li.current_page_item > a:hover { color:#dd3333; }header nav > ul > li.current_menu_item > a:hover { color:#dd3333; }header nav > ul > li.current_menu_item > a:hover { color:#dd3333; }header nav > ul > li > a:active { color:#dd3333; }header #logo > a > img { max-width:200px; }header ul.menu > li.h-cta > a { color:#FFFFFF!important; }header ul.menu > li.h-cta > a { background:#e4cbc7; }header ul.menu > li.h-cta > a { border-color:#e4cbc7; }header ul.menu > li.h-cta > a:hover { color:#e4cbc7!important; }header ul.menu > li.h-cta > a:hover { background:transparent; } Cu ) half-filled and fully filled subshell have got extra stability 2p6, 3s2, 3p6, 3d5 4s1!
