NH3 অণুতে 3টি বন্ধন জোড় ও একটি মুক্ত জোড় ইলেকট্রন রয়েছে। এর আকৃতি VSEPR তত্ত্ব অনুযায়ী চতুস্তলকীয় হওয়ার কথা হলেও বন্ধন জোড় -বন্ধন জোড় ইলেকট্রন বিকর্ষণ এর চেয়ে বন্ধন জোড় -মুক্ত জোড় ইলেকট্রন বিকর্ষণ বেশি হয় বলে আকৃতি বিকৃত হয়ে ত্রিভুজীয় পিরামিড হয়। বন্ধন কোণ 109°28' হ্রাস পেয়ে 107° হয়।
