If an element has atoms, in their ground-state, with 6 valence electrons, the element could be: (check all possible answers)

You included no options however the elements with 6 Valence electrons are;

Valence electrons refer to the electrons an element has on its outermost shell. The number of these electrons determines the charge that an electron will carry as it seeks stability.

It also determines which group the element will be in in the Periodic table. Elements with 1 valence electron for instance will be in Group 1 and elements in Group 16 will have 6 valence electrons.

- 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

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
