Which of the following pairs of elements will combine to produce an ionic bond?
A. Lithium and Bromine
B. Oxygen and Hydrogen
C. Carbon and Oxygen
D. Nitrogen and Fluorine

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

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

idk what is it? is this a question that you know the answer or u dont
