Can you have 9 valence electrons?

An element never has more than eight valence electrons, so there can't be more than eight dots per atom. Q: Carbon (C) has four valence electrons.

Why does fluorine have 9 electrons?

The number 9 is up in the left corner because fluoride is the 9th element on the periodic table. Oh, that's also how many protons are in the nucleus and how many electrons are in the cloud of a fluorine atom.

What atom has 9 protons electrons and neutrons?

By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

What are atoms 9?

Atoms are indivisible particles that can't be destroyed or created through chemical reactions. All atoms of an element have identical chemical properties and mass whereas, atoms of different elements have different chemical properties and masses. Atoms combine in a ratio of small whole numbers to form compounds.

Which element has the atomic number 9 quizlet?

Fluorine has an atomic number of 9.

What elements are an anion?

Oxygen often exists in a neutral state, but oxygen atoms tend to form anions by gaining two electrons. Atoms of other elements also tend to form anions, including nitrogen, chlorine, and fluorine, among others. By contrast, atoms of calcium, magnesium, aluminum, and sodium tend to lose electrons and form cations.

What are two anions examples?

  • Ion:
  • (1)Ion may be defined as an atom or group of atoms which carries positive or negative ions.
  • (2)Ions carrying positive charge are called cations while those carrying negative charge are called anions.
  • The two examples of anions are Br - (bromide ion) and Cl - (chloride ion).

What elements are found in anions?

Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).

Can sulfur have 10 electrons?

So in addition to being octet, sulfur can expand octet to have 10 or 12 electrons.

Do all atoms have 8 electrons?

Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.

What atom has 7 electrons?

A nitrogen atom contains 7 protons, 7 electrons and 7 neutrons.

Does a sodium ion have 10 electrons?

Sodium has 11 protons and electron arrangement of 2,8,1. Sodium has one electron in its outer shell, which it loses, so its outer shell is full (2,8) and it has a charge of +1, as it still has 11 protons (positive charges) and now has only 10 electrons (negative charges).

Can sodium have 10 electrons?

A sodium atom, for example, has 11 protons and 11 electrons. A sodium ion has 11 pro- tons but only 10 electrons.

Does zinc have 10 valence electrons?

So, the no. of valence electrons in zinc are 2.

What atom has 9 neutrons?

Oxygen atoms with 9 neutrons would have a mass number of 17 (8 p+ + 9 n0), meaning they would have a mass of about 17 amu. Oxygen atoms with 10 neutrons would have a mass number of 18 (8 p+ + 10 n0), meaning they would have a mass of about 18 amu.

How many electrons are there in the atom in number 9?

This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.

Is fluorine an anion or cation?

How many electrons would an element have if it has 9 protons?

If we assume the Flourine atom starts out neutral then it will have 9 electrons. Taking away electrons makes Flourine positively charged, but it is still Flourine because it has 9 protons.

What atom has 7 protons and 9 electrons?

#7 - Nitrogen - N.

What negative ion has a charge 1 and 9 protons?

A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.

How many electrons are in an ion with 10 electrons and a − 1 charge?

The ion with a -1 charge is formed when a neutral atom gains one electron. According to the given condition, an ion has 10 electrons and a -1 charge. So, the atom must have 9 electrons originally as one electron has gained. A neutral atom has the same number of protons and electrons.

What are basic anions?

In basic salts, the anion is the conjugate base of a weak acid. In general, anions A- can be considered the conjugate base of the acid HA. Depending on the strength of the corresponding acid: • A-, the conjugate base of a weak acid, acts as a weak base.

What is the charge of an atom with 9 electrons and 10 protons?

If a particle has 9 protons, 9 electrons and 10 neutrons, it is neutral.

What has 8 protons and 9 neutrons and 10 electrons?

17O2− has 8 protons, 9 neutrons, and 10 electrons.

Can a shell have 9 electrons?

Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Can an atom have 9 valence electrons?

An element never has more than eight valence electrons, so there can't be more than eight dots per atom. Q: Carbon (C) has four valence electrons.

Which molecule has 9 carbon atoms?

Cyclononane is a ring of nine carbon atoms.

Does fluorine have 9 valence electrons?

For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge.

Can oxygen have 9 valence electrons?

Thus, the total number of valence electrons present in an oxygen atom is six.

Why does it have 9 valence electrons?

Re: Valence Electrons

The valence electrons are considered to be all of those written after the preceding noble gas configuration. Since there are 9 electrons after the noble gas configuration of Argon, Cobalt has 9 valence electrons.

Which Shell has 9 orbitals?

There are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell. The n = 3 shell, however, also includes 3d orbitals.
