This is false because sodium gives fluorine its electron, and this is an ionic bond. Covalent bonds only form between two nonmetals
Lithium has one available electron in the outer (valence) shell (2s¹).
1s² 2s¹
The two types of data are Qualitative and Quantitative data. Qualitative data is the data that cannot be quantified or measured where as quantitative data is quantified that is measured in terms of numbers.
The given statement 17 birds drink from the pond over the course of 2 hours describes the number of birds that drink water over a given amount time. So, it represents quantitative data. Hence the given statement that The following statement describes qualitative data: 17 birds drink from the pond over the course of 2 hours is false.

Your answer is......... with little bit explains....and read correctly.......The nitrogen is sp3 hybridized which means that it has four sp3 hybrid orbitals. Two of the sp3 hybridized orbitals overlap with s orbitals from hydrogens to form the two N-H sigma bonds. One of the sp3 hybridized orbitals overlap with an sp3 hybridized orbital from carbon to form the C-N sigma bond. The lone pair electrons on the nitrogen are contained in the last sp3 hybridized orbital. Due to the sp3 hybridization the nitrogen has a tetrahedral geometry. However, the H-N-H and H-N-C bonds angles are less than the typical 109.5o due to compression by the lone pair electrons.
