Which elements form covalent bonds? Which other element is included in the group?

Answers

covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom. In general, ionic bonds occur between elements that are far apart on the periodic table.

a. 64.1 g of aluminum ans: 2.38 mol Al show work

Answers

Answer:

2.38 mol of Al

Explanation:

To find the number of moles in a substance, you simply divide by the atomic mass. In this case, the conversion table would look as follows:

[tex]\frac{64.1 g}{1}[/tex] * [tex]\frac{1 mol}{26.98 g}[/tex]

The gram units cancel, and you are left with the answer of about 2.38 moles of Aluminum.

The mass of an atom Is found by adding Its protons and .The electric charge of an atom Is found by adding the charges carried by Its protons and .​

Answers

Answer: the 1st answer is neutrons and i think the 2nd is nucleus

Explanation:

The mass of an atom is found by adding its protons and neutrons. The electric charge of an atom is found by adding the charges of its protons and electrons.

What is atomic mass?

The atomic mass of an element is the total number of protons and the number of neutrons carried by one atom of that element. The atomic mass of an element is usually expressed in grams or a.m.u.

The atomic mass of an element = No. of protons + No. of neutrons

or

The atomic mass of an element = No. of electrons + No. of neutrons

The atomic number gives us information about how many protons are inside the nucleus of the atom. Elements are recognized by the number of protons in the nucleus. Neutrons are uncharged elementary or subatomic particles that are stable when bound in an atomic nucleus.

As the electrons and protons are charged particles in an atom, therefore, the sum of the charge carried by them is equal to the electrical charge of the atom.

For a neutral atom, the number of protons present in an atom is always equal to the number of electrons.

Answer/Explanation:

A theory has lots of scientific evidence to back it up. We know this to be true based on lots of different diseases and studies of their spread.

A hypothesis is more of a starting point - an educated guess based on limited evidence. It requires further testing before becoming a theory.

A law is something that can be generalized to lots of contexts, and is universal. Such as the law of thermodynamics.
