Which of these is the correct lewis structure for a sodium atom

Explanation:

1. To draw the Lewis structure for the Na, first look in the periodic table the atomic number of the Na.

Atomic number of Na = 11

2. Find the electronic configuration of the Na:

As the Na has 11 electrons its electronic configuration will be:

3. As the level three of the Na has only one electron, it means that the sodium has only one valence electron and its Lewis structure will be represented as:

where the dot represents its valence electron.

no statements shown

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
