-You are studying a sample of an element. You determine that the element's atom has 5 protons, 5 electrons, and a mass number of 11. You determine
this is a boron atom. How many neutrons does it have?

6

Explanation:

The mass number is the sum of the number of protons and the number of neutrons so 11-5=6

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
