Answer:

3. 39 39 54

Explanation:

Atoms are the smallest units of matter that have the characteristics of a chemical element. They consist of small particles called protons, electrons, and neutrons.

Protons are positively charged particles that make up the nucleus of the atom along with neutrons, neutrally charged particles. Their mass is almost the same - about 1 AMU (atomic mass unit). Electrons, the negatively charged particles, are much lighter than them and don't significantly contribute to the mass of the atom. Their mass is equal to about 1/2000 of the mass of a proton or neutron.

This is why we need to determine which atom out of the ones you were given has the highest number of protons and neutrons. The first has 91, the second 90, the third 93, and the fourth 91. This means that the third atom has the highest mass.

Decide which element probably forms a compound with oxygen that has a chemical formula most and least similar to the chemical fo
mafiozo [28]

Answer:

Most similar   -----  Lithium

Least similar   ----  Nitrogen

Explanation:

Cesium is an element on the periodic with the atomic number 133. It lies in group 1 (i.e., the alkali metals) and period 6 on the periodic table. The oxidation state of group 1 metals is +1. Cesium forms an oxide with oxygen as  Cs_2O.

The most similar compound to this chemical compound is Lithium because Lithium happens to be in the same group one metal with Cesium and forms the compound Li_2O with the oxygen

The least similar compound nitrogen due to fact that it is an oxide that is covalent in nature and lies between-group 3 -17  to form an NO_2 with oxygen.

Spell out the full name of the compound.
Natalka [10]

Explanation:

Step one look for the longest chain of carbon atoms

Longest chain is 7 C atoms

Step 2 look for double bonds or others functional groups

it is present in 3rd carbon

Therefore IUPAC name is 3-heptene

From point of stereochemistry it can also be written as trans-3-heptene as the hydrogens are placed in opposite side of the C=C bond.

Hope this helps...
