The two central ideas of the scientific revolution were empiricism, which emphasizes observation and experimentation to gain knowledge, and the heliocentric theory, which proposed that the Earth and other planets revolve around the Sun rather than the geocentric model that had been accepted for centuries.
The pair of ideas central to the scientific revolution were empiricism, the idea that knowledge should be based on observation and experience, and skepticism, the questioning of accepted beliefs and ideas in order to seek truth through logical reasoning and evidence.
The pair of ideas central to the scientific revolution was the use of empirical observation and experimentation to understand the natural world, along with the idea that natural phenomena could be explained through natural laws and principles rather than divine intervention. This shift in thinking laid the foundation for modern scientific inquiry and method.
The central pair of ideas in the Scientific Revolution were empiricism, which emphasized the importance of direct observation and experimentation in forming scientific knowledge, and the heliocentric model of the universe, which proposed that the Earth and other planets revolved around the Sun. These concepts challenged traditional views rooted in religious and philosophical beliefs, paving the way for a new era of scientific inquiry and discovery.
NF3 has four charge clouds, consisting of three bonding pairs and one lone pair around the central nitrogen atom. This results in a trigonal pyramidal molecular geometry for NF3.
A pair of tweezers or forceps are commonly used scientific tools that can hold small objects securely while working with them. They provide precision and control when handling delicate materials in laboratories or research settings.
Observation and experimentation.

A lone pair apex refers to the central atom in a molecule that possesses a lone pair of electrons. These electrons are not participating in bonding with other atoms and instead are localized on the central atom. The lone pair apex influences the geometry and reactivity of the molecule.
One lone pair. The central atom is N (nitrogen) which has 5 valence electrons. Three of them are shared with 3 hydrogen atoms, leaving 2 electrons (1 lone pair) on the N.
EGG=(#lone pair electrons)+(# of bond pair electrons)
The question is not answerable. There is NO central atom in C2H2 (ethyn) and there's NO lone pair. All electrons are covalently shared in pairs: three pairs between C and C, one single pair in each C and H bond.
electron pair geometry: octahedral molecular geometry: octahedral
Octahedral
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
The electron pair geometry of Br3 (tribromide ion) is trigonal planar. This is due to the presence of three bromine atoms bonded to a central bromine atom, with no lone pairs on the central atom. The arrangement minimizes electron pair repulsion according to VSEPR (Valence Shell Electron Pair Repulsion) theory.
