What has 6 protons and 6 neutrons and 6 electrons?

What has 6 protons and 6 neutrons and 6 electrons?

carbon atom That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.

What is the total charge of 6 protons 6 neutrons and 6 electrons?

When protons are greater than neutrons the atom is a positive charge or cation. When the protons are less than the electrons the atom is a negative charge or anion. For this example the Carbon atom has 6 protons and 6 electrons making it neutral.

What is the mass number of an atom with 6 electrons and 6 neutrons?

A neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons).

What isotope has 6 protons and 6 neutrons?

Carbon-12 Carbon-12: with 6 protons and 6 neutrons and an atomic mass of 12.

Is melanin carbon based?

Melanin Chemical Structure Like many substances in the body, the chemical makeup of melanin includes a mixture of carbon, hydrogen, oxygen and nitrogen. The melanin chemical formula is C18H10N2O4, giving melanin a molecular weight, or molar mass, of 318 grams per mole (g/mol).

What is the atomic number of 6P and 6N?

The atomic number is 6, for carbon. The atomic number is equal to the number of protons.

What is the atomic number of an atom that has six protons six neutrons and six electrons quizlet?

Carbon-12 is the most common isotope of carbon. It has 6 protons, 6 neutrons, and 6 electrons. Of its 6 electrons, 4 are valence. How many covalent bonds can a carbon atom form?

Which nucleus is from an isotope of an atom with the nucleus 6N 6P?

Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N).

What is element 6 on the periodic table?

Carbon Carbon – Element information, properties and uses | Periodic Table.

What are the 3 types of melanin?

In humans, melanin exists as three forms: eumelanin (which is subdivided further into black and brown forms), pheomelanin, and neuromelanin.

Do all humans have melanin?

Everyone has melanin. Our unique skin tones aren't a matter of having melanin or not, but a result of the amount, type, size, and distribution of melanin our bodies are genetically predisposed to produce. Melanin is created by cells called melanocytes, of which we all have a similar amount, says dermatologist Dhaval G.

How do you find the atomic number?

The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.

Which of the following is the sum of the numbers of protons and neutrons in an atom?

The sum of the number of protons and neutrons in an atom is called the mass number. For example: Carbon-12 has 12 protons and 12 neutrons. 12+12=24 , so the mass number of C-12 is 24 (no units).

What are isotopes examples?

A group of isotopes of any element will always have the same number of protons and electrons. They will differ in the number of neutrons held by their respective nuclei. An example of a group of isotopes is hydrogen-1 (protium), hydrogen-2 (deuterium), and hydrogen-3 (tritium).

What is Group 6 called?

The group 6 elements are called chalcogens and the elements are: Oxygen.

What is Group 6 on the periodic table called?

Lr. Group 6A (or VIA) of the periodic table are the chalcogens: the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po).

What race has most melanin?

African African and Indian skin had the highest total amount of melanin in the epidermis (t-test; P < 0.001), with no significant differ- ence between them. Amongst the remaining lighter groups, there was no significant difference in total epidermal melanin content.

Does white skin have melanin?

Very pale skin produces almost no melanin, while Asian skins produce a yellowish type of melanin called phaeomelanin, and black skins produce the darkest, thickest melanin of all – known as eumelanin.

What color was the first human?

Color and cancer These early humans probably had pale skin, much like humans' closest living relative, the chimpanzee, which is white under its fur. Around 1.2 million to 1.8 million years ago, early Homo sapiens evolved dark skin.

Which skin colour is most attractive?

light brown skin A new study by Missouri School of Journalism researcher Cynthia Frisby found that people perceive a light brown skin tone to be more physically attractive than a pale or dark skin tone.

How do u find neutrons?

To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.

How do you find the atomic number and protons and neutrons?

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Which of the following statements solve for the number of neutrons present in the nucleus of the atom?

1 Answer. Callum S. To calculate the number of neutrons in the nucleus of an atom is simple. You take the atomic, or proton number of the element, and you subtract it from the element's mass number.

Are all atoms isotopes?

All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes.

What is isotope short answer?

An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties.

What is 6 on the periodic table?

What ethnicities have olive skin?

This skin type rarely burns and tans easily. Type V pigmentation is frequent among populations from the Middle East, parts of the Mediterranean and Southern Europe, Romani people, parts of Africa, Latin America, and the Indian subcontinent. It ranges from olive to tan, Middle Eastern skin tones.

Are freckles melanin?

Freckles are the result of an overproduction of melanin. Melanin is a pigment that gives your hair, skin and eyes (your “complexion”) its color. Melanin, produced by skin cells called melanocytes, protects your skin from sun damage by absorbing and reflecting ultraviolet light (UV).
