It is false, the atomic number is the number of protons and/or electrons in an atom on an element.
B. a circle graph
circle graphs are the best to show percentages because they’re very easy to look at and get info from
Cellular respiration releases stored energy and glucose molecules and converts it into a form of energy that can be used by cells
Answer:
Sodium (Na) has atomic number 11.
The correct answer is ClO, ClO3-, ClO- and ClO4-
Kossel and Lewis in 1916 developed an important theory of chemical combination between atoms known as electronic theory of chemical bonding. According to this, atoms can combine either by transfer of valence electrons from one atom to another (gaining or losing) or by sharing of valence electron in order to have an octet( 8 electron) in their shells. This is known as octet rule.
In ClO2-, oxygen contains 8 electrons in its valence shell and oxygen will share one electron with chlorine to complete the octet of Cl. In other four, we can clearly see that there are more or less than 8 electrons in the outer shell of oxygen so we can clearly say that ClO, ClO3-, ClO- and ClO4- are disobeying the octet rule.
