Answers:<\/h3>\n\n\n\n\n
How many electrons can a d sublevel hold?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
A d sublevel can hold 10 electrons<\/strong>.<\/li>\n<\/ul>\n\n\n\n\n
How many electrons can fit in the fourth energy level?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
The fourth energy level can hold up to 32 electrons<\/strong> (2 in the 4s, 6 in the 4p, 10 in the 4d, and 14 in the 4f).<\/li>\n<\/ul>\n\n\n\n\n
What is the electron configuration for N (Nitrogen)?<\/strong><\/li>\n<\/ol>\n\n\n\n
This is the same as the noble gas Argon (Ar)<\/strong> because ( K^+ ) loses its single 4s electron.<\/li>\n<\/ul>\n\n\n\n\n
How many total electrons does the ( K^+ ) ion have?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
The neutral potassium atom has 19 electrons<\/strong>, but after losing one electron to form ( K^+ ), it has 18 electrons<\/strong>.<\/li>\n<\/ul>\n\n\n\n\n
How many valence electrons does silicon have?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
Silicon (Si)<\/strong> has 4 valence electrons<\/strong> (in the 3s and 3p orbitals).<\/li>\n<\/ul>\n\n\n\n\n
What charge does the ( N ) ion have?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
Nitrogen ion (N)<\/strong> forms a ( N^{3-} ) ion<\/strong> because it gains three electrons to complete its octet, giving it a -3 charge<\/strong>.<\/li>\n<\/ul>\n\n\n\n\n
What are the Group IA elements called?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
Group IA elements are called alkali metals<\/strong>.<\/li>\n<\/ul>\n\n\n\n\n
Which element in the fourth period is a halogen?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n
Bromine (Br)<\/strong> is the halogen in the fourth period.<\/li>\n<\/ul>\n\n\n\n\n\n\n\n
Explanation (300 Words):<\/h3>\n\n\n\n
The periodic table is structured into energy levels, sublevels, and groups, which determine the properties of elements. The d sublevel<\/strong>, which appears in transition metals, can hold a maximum of 10 electrons<\/strong>. The fourth energy level<\/strong> consists of four sublevels: 4s (2 electrons), 4p (6 electrons), 4d (10 electrons), and 4f (14 electrons)<\/strong>, summing up to 32 electrons<\/strong>.<\/p>\n\n\n\n
The electron configuration of an element describes how electrons are distributed among its atomic orbitals. Nitrogen (N)<\/strong> has the configuration ( 1s^2 2s^2 2p^3 )<\/strong>, meaning it has five valence electrons. Potassium (K)<\/strong> normally has 19 electrons<\/strong> with the configuration ( 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 )<\/strong>. However, when it loses one electron to form ( K^+ ), its electron configuration becomes the same as Argon (( Ar )), meaning it has 18 electrons<\/strong>.<\/p>\n\n\n\n
Silicon (Si)<\/strong>, located in Group 14, has 4 valence electrons<\/strong>, making it crucial in semiconductor technology. Nitrogen ion (N\u00b3\u207b)<\/strong> forms by gaining three electrons<\/strong>, acquiring a -3 charge<\/strong> to achieve a full outer shell.<\/p>\n\n\n\n
The alkali metals (Group IA)<\/strong> include elements like Lithium (Li), Sodium (Na), and Potassium (K)<\/strong>, known for their high reactivity. In Period 4<\/strong>, the halogen element is Bromine (Br)<\/strong>, known for its chemical reactivity in forming salts.<\/p>\n\n\n\n
This structure of elements governs their chemical behavior, explaining why elements form ions, react with others, and maintain stability.<\/p>\n\n\n\n
