Answer:
There are 26 valence electrons in SOF₂.
Explanation:
Valence electrons are calculated by adding the valence electrons present in valence shell of each element present in SOF₂. So,
# of Valence e⁻s in S = 6
# of Valence e⁻s in O = 6
# of Valence e⁻s in F = 7
# of Valence e⁻s in F = 7
Now, add all valence electrons,
= 6 + 6 + 7 + 7
= 26 Valence Electrons
Answer:
B. away from each other
Explanation:
It is the result of a divergent plate boundary that runs from 87° N – about 333 km (207 mi) south of the North Pole – to 54 °S, just north of the coast of Antarctica.

Answer:
B)
Explanation:
Dalton was the first scientist to propose an atomic model. He said that each element is composed of extremely small particles called atoms, which are indivisible, atoms of a given element are identical, and atoms of different elements have different properties.
With the advance of the studies, it was proven that elements are composed of small particles, atoms and that the atoms of each element are identical, and have different properties from atoms of different elements.
But, now we know that the atom can be divisible: it's formed by electrons, protons, and neutrons. So only postulate <em>ii</em> is no longer considered valid.
