Answer:
B.) Oxygen is usually -2
Explanation:
Hydrogen is usually +1.
A pure group 1 element is not always +1.
A monoatomic ion can be a range of numbers. However, it must be a charge other than 0.
Answer:
Sp3
Explanation:
Hydrocarbon can be defined as an organic compound that comprises of hydrogen and carbon only. Some examples of hydrocarbon are methane, butane, ethane, ethene, etc.
Hybridization can be defined as a phenomenon which involves the combination of two or more atomic orbitals to form the same number of hybrid orbitals, with each of the orbitals having the same shape and energy.
In Organic chemistry, ethane is considered to be a tetrahedral carbon and it's Sp3 hybridized.
A tetrahedral carbon typically comprises of four bonds that are 109. 5° apart while a linear carbon atom comprises of two (2) bonds that are 180° apart.
Hence, the molecule of ethane posses a Sp3 hybridization because it has four bonds arrange with a tetrahedral geometry.
Answer:
It shows no regular pattern
Explanation:
Physical properties of an element are those we can observe and feel with our senses. Also, the use special equipment can enhance our perception of these properties.
- The same physical property can be shared different number elements.
- On the periodic table, all the elements in group 1 and 2 are metals.
- This is not very useful for scientists whose emphasis is to distinguish one atom from the other.
- Therefore, physical properties are highly limited in the organization of the periodic table.
Answer:
My dream school would be a school where the teachers were all friendly, positive, and kind. My fellow students would be equally enthusiastic and hard-working students. It would be a spacious building, with plenty of student parking spaces and lots of outdoor space for relaxing.
