1. bc valence electrons are the amount of electrons on the outer shell of the bohr model. if you look at the periodic table from left to right they are numbered 1-8 the columns. this stands for the valence electrons, sodium's being 1

Answer from: brasherfamily14

Sodium has one valence electron

Valence electrons are the outermost electrons, and are the ones involved in bonding. Sodium has 11 electrons: its atomic number is 11, so it has 11 protons. Atoms are neutral, so this means that sodium also has 11 electrons

Electrons are arranged in shells or energy levels.
The first evel can have 2 electrons;
The second level can have up to 8 electrons.
The third level can have up to 8 electrons as well

So, sodium´s 11 electrons are arranged this way - 2 electrons in the first shell or level; 8 electrons in the second level; and 1 electron (the valence electron) in the third level.

The correct way to write this is 2.8.1 - The last number is how we know the number of valence electron.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

Answer from: Quest

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
